1. What is the difference between thin client & thick client? Thin Client is a browser based version, whereas thick client is a desktop based version. In thick client, you have lot of functions and formatting options. Desktop Intelligence is full client. It is 2 tier architecture, where Web-I is 3 tier with Enterprise server in between. Desktop-I and Web-I differs in some syntaxes. E.g: [] in Web-I, <> in Deski. Also scheduling can be done directly in Web-I (Xi R2), where as we need additional software to schedule Deski reports. You can view the Deski reports in Web-I, but not Web-I reports in Deski. But we can schedule the Deski reports via Web-I. WebI: it is 3tier architecture. and also known as thin client . in boxir2 wise merge option available,edit sql also. scheduling directly, Reports will generate not only corporate doc's, others also(excel,pdf--),hide option is not available, Deski: it is 2 tier architecture & also known as full client. Here hide option, edit Sql, rank options are available. Desktop intelligence reports are dynamic. desktop intellegence is window base tool and need installation on every PC where as WebI is web base tool and can be access any where through interenet

explorer Crystal reports are static and pagewise. Infoview: WebI is a part of infoview. it generates java based reports. while open the reports through infoview. 2. In BOXIR2 we have following tools. Import Wizard Report Conversion Tool Repository Migration Wizard 3. Multi pass SQL: Multipass: Breaking one large SQL into multiple SQLs.If you are using the star schema with two or more fact tables,and you enable this feature, BO will automatically generate two or more SQLs (i.e. one SQL for each fact table object used in the report). Then the results will be synchronised in the report. 4. what is isolated joins in check integrity Isolated join is the join which is not included in any of your contexts, so you are getting that error. Solution : First of all find what are all the joins you left with out including in any of your contexts and join them to any of the context which you thnk appropriate. 5. Migration Process: To migrate the bo 6.5 to XIR2:-- a) open the migration wizard b) select ur source location(Here give ur BO 6.5 doc) c) click next

d) select ur destination location (ur BoXIR2 environment) e) select the users or admin or specific users f)click next f) click ok. 6. Difference b/w Break & section? Break removes duplicates but the same thing cannot be done by section. Break displays data within the same cell content and Sectioning appears outside the grid. When you do any arithmetic operation on break say sum or count, you can see the sum for individual block and for all the blocks in bottom. In Section it performs operation only on individual block. 7. What is master-detail report? Master-Detail report allows us to display the result in Section wise. It splits large blocks of data into sections. It minimizes the repeating values. We can have subtotals also. It displays the data section wise. If you have the following in a report, for e.g. Country, Store, Sales, you can change it into a master detail report country wise by dragging and dropping Country as a section when the cursor shows the text 'Drop here to create a section' you can seethe data country wise. 8. how big is ur team in my enviroment their are 1500 Business End Users and 4 report Developers and Two Universe Designer and one Administrator. 9. is it possible to creating reports without universe. it is possible to creating reports without universe. By Using personal data files&free hand sql By Using personal data files&free hand sql. This is possible only in deski reports not in WebI. 11. how to solve #multivalue, #syntax, #error. iwant complete solution process in practical wise? #Multivalue :- this error will occur in 3ways 1) #multivalue in aggregation 2) #multivalue in breaks header or footer 3) #multivalue in section level. 1:-- the o/p context not include i/p context its situation this error occurs. Ex: in a report i have year,city dia's & Revenue measure is there. =<revenue> In <year> The above condition will to run the query getting revenue column #multivalue error occurs. solution: cilck the formulabar in view menu select the error containg cell, edit the formula to write below condition. = <revenue> In(<city>,<year>) In <year> The above formula will run correct data will appear in the report. Note: the above condition by default it will take agg "sum" function. #syntax:-- the variable in the formula no longer exist in the condition.

Ex:- <product price> * <quantity sold> The above condition will run this error will occur. Solution:- Click edit dataprovider--> new object will be need --> select error cell --> edit formula --> click ok. #error:-- the variable in the formula is incorrect. this error will occur. solution : go for data menu --> click variable select the error containing a cell --> copy the formula in edit menu --> paste it in new cell --> go for formula bar in view menu --> --> take the first error containg cell -->edit the formula --> repeat the above steps. 12. What is the difference B/W Variable & Formula? Whenever we execute the formula , the result will be stored in the variable. 13. what is ment by incompatable object error in the report level? When the contexts are not properly defined we will get the error as incompaitable combination of objects. 14. In a report i want to fetch teh data from 2 data Providers. which condetion wil satisfy to link the 2 data providers. ex: Q1 have columns A,B,C Q2 has a X,Y,Z columns. requirement is like i want to get all the columns from those 2 tables in report level..like A,B,C,X,Y,Z in a single report. in BOxir2 wise it is possible. would u have base uni & dervied uni's. i think ur requirement is solve by using "combining query" option & just select "union" operator wise ur query is solve. anotherwise u go for WebI, select "MERGE" option it is possible. otherwise, ur requirement is not possible. because ur columns names are not maching. u go for deski, select "datamanager" --> click "link to" Option it is possible. 15. What is meant by For each For all function. In which case we use the option in BO? for each-add all objects to the contex for all-delete all objects from the context we use forall for summary purpose and foreach for detail purpose 16. how we improve the performance of report and universe? By creating the summary tables and using aggregate awareness. 17. In xir2 how to send reports to end user You can send reports to any user via the scheduling options for a report. The report will then run as per the scheduled options and when successful, it will send a copy to the user's email address or inbox (in BO), depending on the options selected.

18.which is the best way to resolve loops? Context or Alias? in a schema we have only one look loop u can create Alias. But, when we have multiple look up u can create contexts. most of the cases are using context can be use to resolve the loops. why because more number of complexity loops and also schema contains 2 or more fact tables in ur universe design. If there are more than one fact table use a context or if only one fact table use alias. 19. How do we link 2 universes? The linking can be done at reporter level by linking of data providers. We can link the dimensions and measures of two different universes with 2 different connections by linking the data providers built upon them. 20. What r the types of joins universe supports? Inner Join, outerjoin, left, right outer join, full outer Join. 21. What r the universe connection types? Shared connection Secured connection Personal connection - used only stand alone system. 22. what r the advantages of creating the universe? The main fact behind creating universes is "Business users need not have strong SQL back ground. But sometimes they need to develop reports". In such case the importance of universe comes. The universe designer needs to have a strong SQL back ground and he/she will create universe which in turn has objects like dimensions, measures, etc,... The business user then uses these objects just by dragging and dropping in the query editor pane. Dragging, dropping and running is more easy for him rather than writing SQL by his own. 23. How do u drag 2 sources from 2 diff data providers, how we take these 2 sources into 1 single report? By using data synchronization Option.... synchronization is the term used to describe the merging of data from multiple data sources into a single block in a report 24. what is merged dimension in 6.5 and webi? in xi r2 they introduced Merged dimension concept to synchronize the multiple data providers in webi by merging them on common dimension... 25. Aggregate Awareness? Aggregate awareness is a term that describes the ability of a universe to make use of aggregate tables in a database. These are tables that contain pre-calculated data. You can use a function called @Aggregate Aware in the Select statement for an object that directs a query to be run against aggregate tables rather than a table containing non aggregated data. Using aggregate table‟s speeds up the execution of queries, improving the performance of SQL transactions. The reliability and usefulness of aggregate awareness in a universe depends on the accuracy of the aggregate tables. They must be refreshed at the same time as all fact tables. A universe that has one or more objects with alternative definitions based on aggregate tables is said to be “aggregate aware”. These definitions correspond to levels of aggregation. For example, an object called Profit can be aggregated by month, by quarter, or by year. These objects are called aggregate objects. Queries built from a universe using aggregate objects return information aggregated to the appropriate level at optimal speed. 26. What is BO Main Key? BO Main key will store the address for repository of the security domain. General path for BOMainKey C:\Program Files\Business Objects\BusinessObjects

Enterprise 6\LocData 27. How to Link 3 fact tables? Fact tables are tables with lots of measure values and are uniquly identified by a key, also a fact table can have a foreign key. For Example custumer fact table is connected to loan fact table via customer_id, and each record in loan fact table is uniquely identified by a primary key on cod_acct_no. Similarly customer table can be connected to Savings fact table through customer id. 28. What is hierarchy & Drilling? Heirarchies will be used in drill reports. We will select Drilling levels in Query panel. There are 4 types of levels are there. 1.level 2.level 3.level3 4.custom level drill down --->navigation of levels,like one by one drill through--->selecting new level of heirarchy at the time drilling drill by--->directly selecting required drilling level so,from your point a-b-c is drill down a-->c is drill by 29. How to Hide rows & columns in a report ? hide the colomn --- menu>formate>table formate>pivote>hide button, Rows can be hide only when the break is applied on a particular column using... Format-->Breaks-->Fold 30. What do u mean by Merged dimensions in B.O.? merged dimension is nothing but to synchronize the data from different data sources with a common dimension. Web Intelligence allows you to synchronize multiple data providers in the same document. This allows you to build reports which synchronize data from multiple sources. When you synchronize queries through merging, you can include report objects from different queries in the same report block. 31. What we have to do to increase performance tuning & to decrease the response time of a report. if we run a report it is taking so much time to display the result to be fallowed as : 1) use aggrigate tables(contains pre caliculated data) 2)pre defined conditions,LOV's 3)Summary tables. in a real time scenario query contains a large if statements. some times we need to wait max of 30 min to run perticular statement...not all If the question is not pertaining to query optimization, I would prefer not to use much of formatting on the page. One

can keep the report without formatting. Try not to use the slice & dice panel as this would also take considerably long time. 32. What is Full path Client? Full path client is nothing but an info-view. 33. How to sort on a particular object, that object is not picked up while creating the cross tab but we need to sort on the object that is not in the cross tab???? Go to Format--Sorts then click on Add. We will get all the objects select the object and apply it which is not in the Cross tab report. 34. How can we retrieve particular number of rows from data ware house? For EX: my report wants to display with 10 records in a report? How? We can do this in 2 levels in BO. 1. In Universe parameters, set the no of records for your requirements. But I will apply to all reports. 2. We can do this to a particular report in the query panel. Select OPTION button (Left side down placed) and set the no of records how many you want. 35. What is custom sorting? Custom sorting is nothing but sorting as per our requirement suppose months like jan feb mar apr may jun jul We can display first jan next mar next jun for these purpose we can use custom sort 36. How do we apply sql query on selected variables? If u drag the variable, automatically sql query will be added. Or if u select new variable, one window will appear. In this window u select the qualification (dimensional or detail or measure) in definition window. Go for formula tab, window will appear here write a formula by using objects & operators. if u have any errors or not plz check once parse condition. Click apply > click ok. 37. what are the differences between web intelligence reports and crystal reports ? bo reporting is prefered for dwh,where as crystal is preffered for transaction database which involves lots of queries and joins. webI : it is ad-hock reporting. we can change the report as per reqirement for managenment quick dessions.for management Crystal Reports: it is standered reporting daily transactions(example bank ,shopping malls) for production users. 38. What is Fan Trap & Chasm Trap? 1) FANTRAP PROBLEM solved by ALIAS METHOD: Definition: Two One-to-many table link eachother is in turn

linked another one-to-many table. 2) CHASM TRAP PROBLEM solved by CONTEXT METHOD: Definition: Two Many-to-one table converges on one single lookup table. Loop can be detected while INTEGRITY CHECK is done. An option is there as "Check for LOOPS" available. By "Detect Loop" we can choose what to be applied for solving the loop. 39.How do u migrate from 6.5 to XI ? migration is done with the help of import wizard in xir2. other wise u can manually migrate universe or report. when u try to open a 6.5 or 5x version report or universe they will automatically updated to xi and they cannot open again in the previous version once they converted to xi. that is why it is better to take a back up before migration. 40. What is metrics? A metric is the measure of actual performance. A metric is defined using objects in the universe. These are used to track trends and productivity 41. What is Dashboards? Dashboards is nothing but collection of information 42. IN BOXIR2 creating universe by using Designer and Business View. What is the difference b/t two? Business view is used to create a lovs in crystal reports. This can be schedule to refresh to daily. business view can be used by only in crystal reports a universe can also be a source for crystal reports as well as web intelligence. in business view we can connect to multiple database and create a business view, it is not there in universe 43. Why do we use crystal reports rather than web intelligence reports? Crystal reports: we use most of the times daily basis. we have to know the day to day status. Example daily transaction of the persons in a bank. End of the day whole sales reports of the same branch. It is for production .it is a predefined template Web I: it is only for manage ment users. they want to take own decessions for their own like take a sales mall giving offers like end of season sale and clearence sales occational offers. Webi report- it is ad-hoc report, we can modified as per request and analysis the reports. but in Crystal reports--> we cant not modify the reports and it contains daily bases i.e., day to day infromation .example: shopping mall and customer details in bank. 44. What is chasm trap & Fan Trap? Fantrap means one-to-many joins of the tables it is

detected by visval analysis. By using fantrap problem is many rows than expected. Through aliases,context and check mutiple sql statements for each measures option we can solve this problem. chasm trap means two or more many to one joins converge on to a single lookup table Chasam Trap: chasm trap means many-to-one and one-to-many join relation converge on to a single lookup table, because of this we get incorrect results i.e., cartision product, We will resolved by using some times alias, some times context, some times shortcut join and check mutiple context for each measures option. Fan Trap: Fantrap means one-to-many and one-to-many join relation of the tables it is detected by visval analysis, because of this we get incorrect results i.e., cartision product, We will resolved by using some times alias, some times shortcut join and check mutiple sql statements for each measures option. 45. How many universe dfi you create if you have 2 years of experience in BO ? 1. Two Universe 2. Depends on my data base and my project. example.in my project if i have 100 tables i will create 6 universe. any way u have a two years of exp in bO .u dont have chance to create universe.we need min 5 to 6 + exp and good domain knowledge 46. Iam having an report there four cloums and n number of rows if i click ang one cell the report want to go to another report page which gives the detail of the cell which i click pls help me with example This is hyperlinking.The cell can be defined as a hyperlink and parameters can be passed to the destination report to open. 47. Iam having an report it contain n number of rows i want to desplay each rows in one colur Insert a vertical table on the existing table or click drag drop the rows into columns. BY USING ALETER we can display each row in different colour. 48. What are the Errors in BO Pls Explain with Examples #Multi value: When any variable yield more than on result #Syntax: Occurs when we remove any object from report that is used in the formula of nay variable. #Error: Generic Error #Incompatible, Context Error: Generally occurred when we context is not properly defined for calculation and when we try to place two incompatible objects in one table.

#Div: Divide by Zero 49. How to Shedule the reports in Xi R2 You could see the option of scheduling in infoview,right below your report...otherwise u cud schedule it from Central management Console 50. Explain about the different between 6.5 & Xi R2 B.O 6.5:-- > 3tier architecture > Rep created after the installation > In Webi wise :-- > There is no alerters & There is no merge option > In 6.5 Contains 57 tables are there > In security level wise also some changes are there : > in supervisor acess security servies option is there. >In 6.5 There is no Casading prompt. > Here separate Supervior & B.C.A BOXIR2 : Desiner wise-- > directly to restict data in designer level. > New feautuer is Cascading prompt Webi wise : > here alerters & sub alerters also possible > Merge Option is also possible > BCA + Supervisor combined in CMC. >doc domain & uni domains are located in form of folders > here secured & Saved in folders & categories. > Sheduled directly in Webi. Architecture wise lot of difference is there between BO6.5 and BOXI. 1. In BO6.5 we have to copy BO. main key in each system to install s/w. For BOXI no need of copying BO. main key. 2. In Bo6.5 Supervisor control all the aspects. While in Bo xi Supervisor is replaced by CMC (Central management console) is take care under CMS (Central Management Service) 3.6.5 is user centric and XI is object centric 4. BO 6.5 is a 3 tier architecture Universe Domain, Document Domain & Security Domain. Where as B.O. XI is 5 tier architecture with Client, Application, Intelligence, Processing and Data tiers. 51. how to restrict null values in webi report? I believe you can define a formula like below Not IsNull(object). This formula should bypass all records that has null values..There might be some other ways too.. 52. how to do scheduling in desktop intelligence in BO XI R2 ? To schedule a Report first you to export the report to the Administrator and select the Folder then select the object and select schedule and you will get the choice to select like once, ondemand , weekly, monthly so on. if you still confusion then go through the Administrative Guide. Once the Report is saved, then click on file, go to Export,

and export the export which you want. Once the report is exported then a small dialog box appears which shows that Exporting is done successfully, then save ok. Now go to Crystal Enterprise (Infoview) and open the report which you exported earlier in Desktop Intelligence. Click on that folder and you can see the Report over there. Then from there we can schedule the report like, daily, hourly, monthly, qtrly, yearly etc....... 53. what is difference between folders and category ? folders: folders and subfolders are used to organize documents categories: categories are a way to classify your information for example, you could place your financial reports and documents into a folder name finance and you could classify or tag your reports that deal with specific financial matters as payroll, accounts, payble and accounts receivable. 54. Tell me about linked universe? a) Linked universes are universes that share common components such as parameters, classes, objects and joins. Among linked universes one universe is said to be kernel or master while the others are the derived universes. b) If the data provided is from two different data providers then we can link those two universes. Such universes are called as linked universes. c) In real time scenario we will work with linked universe. here same data source and diff data source is not a issue. We can fetch max 15 to 17 tables in single universe. More than that u will create another universe and link it. File-->parameters -links d) Concept of linked universes is based on inheritance. You can specify your common classes and objects in Parent universe (Kernel) and then link this universe in child universe (Derived Universe) to make use of these classes and objects. In Derived universe one can add their own tables, classes and objects. However linking universe does not link following... ->Parameters ->contexts ->Aggregation 55. How do you share the universe? By moving it as a file through the file server and exporting it to the repository 56. How do you give security to universe? We can secure the universe by applying security restrictions through Universe Designer. We can apply following types of security restrictions on different users: 1. Object Restriction 2. Row Level Restriction. 3. Table Mapping. 4. Connection Restriction 57. What are zero client and thin client? Zero-client viewers do not require client-side software to be installed or downloaded. Instead these viewers display the reports as DHTML. Thin Client Viewers require components to be downloaded and installed on the client‟s computers. These client viewers offers better report fidelity but can require more administrative overhead

58. What is a Variable? a) Variables are used to prevent the same computation being performed several times as the variable allows you to store the values so that they can be used later. b) A variable represents specific data or a value, and acts as a placeholder for that value. Unlike a constant value, which is fixed and unchanging, a variable can be repeatedly assigned different values. You assign a value to a variable and the variable maintains the value until you later assign a new value. Because of this flexibility, it is necessary for you to declare variables before you use them. Variables can be treated as a normal attribute, that is, it can be a source or target of a transform 59.@prompt ('message', ['type'], [lov], [mono/multi], [free/constraint]) what is Constraint? Free Means, User can either enter value or select value from Lov. Constraint Means, User can‟t enter their value, they should select value from LOV 60. What is a Micro cube? a) A cube contains data in multi dimensional analyzed format. Its components are: 1) Measure / Fact: - It's an object which is been analyzed. 2) Dimension : - It's an object with respect to which we perform Analysis. 3) Detailed : - It's an object which provide extra information about a dimension. b) Micro Cube is a processing Unit. It is composed of facts & Dimensions & measures. Micro Cube is cleared by using "Purge" Option. 61. How to Analyze „Join‟ problem and which method is the best to resolve that? Join problems are analyzed by Integrity checking and resolve by setting cardinalities 62. Say, the query gets executed and we got the results. In case if we have a large number of rows, how can we know the exact no of rows returned? a) From the data manager tab we can know the no of rows returned and the time taken to run the report. b) Click on any column in result set, right click and select count all. This will display the total number of columns in the result set. 64. Is there any way to know how long the report executes and how many records will be returned before hitting the "run" option? a) Go to Definition tab in the data manager there u find these query options. b) Before run a report just click on view button u can see the report. c) Simple! Take the report query and modify to take the count in the query and execute it at the back end. 65. There are 2 types of strategies are there? 1. Built-in Strategy 2. External Strategy. Can you please explain them in complete that what are these? Built-in Strategies: Designer provides a number of default strategies which we can use. These are strategies for extracting joins, detecting cardinalities, and creating default classes and objects. Options for indicating default strategies are located in the Database tab of the Options dialog box. External Strategies: We can also create our own strategies. Such strategies are referred to as external strategies.

With an external strategy, we can specify the exact way that objects and joins are to be extracted from the database structure. The strategy we use, for example, can be a script generated from a CASE Access tool. An external strategy is specific to one RDBMS. b) External Strategies are script files used how to read the data dictionary of source database. Data dictionary of source database having meta data information of tables, columns, views, synonyms, stored procedures etc. 66. What is the difference b/w 6.5 & XiR2? a) 1. XI R2 has a 5 tier architecture, where as 6.5 has 3 tier 2. In XI R2 we have some new tools like Import wizard, conversion tool etc. 3. In 6.5 we have a product called Business objects but now it is been renamed as Desktop intelligence. 4. I n 6.5 we have supervisor, but there is no supervisor in XI and they have introduced the new concept of CMC which is used to created users, user groups etc. 5. In 6.5 reports are being stored in document domain of repository, now they have introduced the concept of folders and categories. 6. In 6.5 we have BCA (broad cast agent)to schedule the repots but in XI there is no BCA, u can schedule the reports using "Scheduler" in CMC 7. Not only these even in designer, deski & webi, u have some new enhancements WEBI:-- In 6.5 there is no "Alerts", In Bo xi having "alerts & Sub Alerts" also b) In Business Objects 6.5 Repositories are created by Supervisor after installing the software, Where as in BO XIR2 by default 3 repositories are created while installing the software. They are central management repository, File repository and Audit repository. 67. How to connect to a server in a business objects There are some third party software are there to connect like "CITRIX" 68. What are slowly changing dimensions & confirm dimensions? a) Slowly Changing Dimensions are basically those dimensions whose key value will remain static but description might change over the period of time. For example, the product id in a companies, product line might remain the same, but the description might change from time to time, hence, product dimension is called slowly changing dimension. Where as confirmed dimensions are some thing, which can be shared by multiple Fact Tables or multiple Data Marts. b) Conformed Dimensions (CD): These dimensions are something that is built once in your model and can be reused multiple times with different fact tables. For example, consider a model containing multiple fact tables, representing different data marts. Now look for a dimension that is common to these facts tables. In this example, let us consider that the product dimension is common and hence can be reused by creating short cuts and joining the different fact tables. Some of the examples are time dimension, customer dimensions, product dimension. c) Confirm dimension: Confirm Dimension which is used to link more then 0ne fact table or data mart. For example In our project, we have created five data mart of different subject area ,our client requirements is to create a report by linking all the data mart or subject area .To achieve that report we linked all the data mart through Person confirmed dimension . d) A confirmed Dimension (CD) is a dimension which is shared by different fact tables.

For examples, there are different data marts are there say Loans, Deposits, Withdrawals etc.....in this there is a dimension called Date which is common to all. We can link to different data marts using a common dimension called Date in this example. e) Confirmed Dimension, it is a dimension linked with two or more fact tables. Suppose we have two fact tables like sales and production link with dimension product dimension here Product is the confirmed dimension f) A dimension that carries the same meaning across the different fact tables is called conformed dimension. Confirmed dimension are a must to put a no. of data marts together to create a enterprise data warehouse g) In the schema a dimension which is shared by multiple fact table that dimension is called confirmed dimension. 70. How do u migrate BO 6.x to XI? There are 2ways to migrate 6.5 to xi. 1) Open migrate wizard. IMPORT WIZARD window appears. Import wizard is a tool to migrate reports, Universes, Repository objects to one environment to other environment with in XI and also from prior versions to XIR2 versions. 2) While using this option, Report Conversion tool. 71. Draw the architecture of traps? a)Fan trap:- Customers----->orders---->order lines b) Chasm trap: Reservation line Service < Invoice line Fan trap: Client->sales->sales model 72. What is the syntax for aggregate awareness? a) @ Aggregate _Aware (sum (agg_table_1), ... sum(agg_table_n)) b) Aggregate awareness is a feature that makes use of predefined aggregate tables to enhance the performance of SQL transactions. It is used to improve the speed by which aggregates are calculated in the database. To set up aggregate awareness in a universe, you define or more objects using the @ Aggregate_Aware function. The syntax for this function is as follows: @Aggregate_Aware (aggregate_table_1, ... aggregate_table_n) c) The arguments of this function are all the names of alternative aggregate tables. When you formulate the syntax, you should be aware of the order of the arguments. The precedence is from left to right; this means that Business Objects determines the aggregate to use beginning from the leftmost argument. 73. What is the Computation error? How to solve it? The computation error is related to the misuse of context operators in formula 74. An index has been done on the primary key of a table. An update operation was performed on that table. Now my question is 1> what about the performance? Means faster or slower due to indexing? 2> does the operation affect to the primary key constraint?

Normally database takes to 2 hours of refresh time. But client asked I want to refresh with in 5 min that same database. Do you have any option in BO and Oracle? Explain me briefly. When we use an INDEX, performance will increases......... In fact the main purpose of index is to increase the performance only.(very fast). 2. The index, generally works based on primary key or unique key. When we use index refreshing time will reduces. 75. You are a universe designer and report developer in BO, what type of information you gather from client? Briefly explain? We can gather information by asking QUESTION TO THE CLIENT like WHAT, WHY, WHEN and HOW. Role of BO Developer is, --->Firstly we have to understand the Business Process and user requirement of the client. --->Based on that we have to design and develop Universe. --->test the universe. --->Finally, view and share reports between end users. 76. 2 tables are there, columns are with different names, but data type is same, 2tables values are same. How to you find out both values are same? In Designer, In the file tab-->parameter-->Strategy We join the two tables. We have lot options to join like „match by column names, match by values‟ etc. 77. Table A, Table B are there, columns are different like table A contain (A varchar (9), B varchar(2), date), table B contain(D varchar(10), E varchar(2), F date) , i want 2 compare mismatch data type length in both table, how? Do you know any in built function? Using describe function v can find out that mismatch data type. Desc table a, table b; 78. What are the degenerated Objects? Objects created using SQL queries or stored procedures called Degenerated Objects. 79. What is input level context and output level context in webi? The input context determines what dimension to go into the calculations to produce the values. Whereas the out put context determines how the values are combined. It is generated by the cell location with the report. 80. What is casual dimension? Casual dimension is a dimension that should not change the fundamental grain of a fact table. Ex: sex- Male, Female. 81. What is the use of Surrogate Key in BO? a) Surrogate Key is a primary key in data warehousing, the only difference between surrogate key and primary key is that surrogate key allows duplicate values and primary key doesn‟t. b) Surrogate key is the dummy key which is used to allow the duplicate values c) Surrogate key is contiguous numbers generated by DB in a table which acts as a primary key since surrogate key has unique values. d). It is used for duplicate values in a database. Primary keys cannot be changed when a unique error occurs. With the help of this surrogate key a new column values will be created and that will be as primary keys. e) Surrogate key is unique key which is used in type 2 dimension.

82. Can we use detail object in generation of reports? If customer id is a dimension in a report, what will happen if we define it as a detail? a) Detail object means it should give detailed information for some dimension object. You can use these objects in your report generation. When we drag the detail object in query panel, It will automatically fetches it's corresponding dimension object also. b) Detail object:- It gives extra information to the dimension object. Eg:-customer id is a dimension object then detail object of customer id is customer name i.e. first name, middle name, last name, Address, Phone number. If we put customer id as detail the only problem is we can't perform drilling on it 83. What is maximum scope of analysis --> can we define more than 3 levels? By default, you can do only up to 3 levels. But with custom, you can do more than 3 levels. 84. Difference between scope of analysis in Webi and in Deski? In Deski: all the data for all objects will be retrieved from the database and that is stored in micro cube. Whenever you want to drill down for next level dimension, it doesn‟t need to connect to the database. In Webi: all values for all objects that are dragged into the query panel will be retrieved. Hierarchical objects values won‟t be retrieved like deski. When ever you drill down the report, to display the values this report is to meet database again and retrieves the data. 85. What is casual dimension? One of the most interesting and valuable dimensions in a data warehouse is one that explains why a fact table record exists. In most data warehouses, you build a fact table record when something happens. For example: When the cash register rings in a retail store, a fact table record is created for each line item on the sales ticket. The obvious dimensions of this fact table record are product, store, customer, sales ticket, and time. At a bank ATM, a fact table record is created for every customer transaction. The dimensions of this fact table record are financial service, ATM location, customer, transaction type, and time. When the telephone rings, the phone company creates a fact table record for each "hook event." A complete call-tracking data warehouse in a telephone company records each completed call, busy signal, wrong number, and partially dialed call. In all three of these cases, a physical event takes place, and the data warehouse responds by storing a fact table record. However, the physical events and the corresponding fact table records are more interesting than simply storing a small piece of revenue. Each event represents a conscious decision by the customer to use the product or the service. A good marketing person is fascinated by these events. Why did the customer choose to buy the product or use the service at that exact moment? If we only had a dimension called "Why Did The Customer Buy My Product Just Now?" our data warehouses could answer almost any marketing question. We call a dimension like this a "causal" dimension, because it explains what caused the event. 86. How to overcome overflow of data in a report a) By giving filters and conditions in the report level. b) OVERFLOW occurs when a calculation returns a value that is too large for Web Intelligence to handle c) Select the properties at the report level and choose appearance from the tab. You can adjust the tables horizontally and vertically. d) When you have huge number of rows in report then u will get partial results in that report. For that you have to increase the (Limit Size of the Results) check box button in Universe Parameters. Then your report will not overflows. 87. Is there any limit for rows and columns in cross tab? No

88. When and where we use @variable function? The @Variable function is used to call the value assigned to variables. The variables are of two types: 1) Business Objects system variables 2) Personal text files variables 89. What is static filter and dynamic filter? In Static filter, record set is filtered based on a table field value. In Dynamic filter, record set is filtered based on the value specified for a specific business object property. 90. What is report tracing in BO? Mainly the tracing concept is coming in designer level. Tracing means if you have 2 tables, if you select one table column drag the cursor to the next table column, at that time cursor will turns into pencil symbol. 91. How many micro cubes can a report have? Only one 92. What is a local filter? A local filter is applicable only to a particular block i.e. the block on which it is created like on a particular table or cross tab. 93. Generally how do we get information for creating universes and reports? 94. What is the difference b/w b.o. 5.1 or 6.5 or Xir2? BO 5.1.2 had no Infoview. BO 6.5.1 included Infoview, but no Crystal Report, CMC not present. Instead supervisor (thick client) was used for giving Users rights. BO XI includes integration with Crystal Reports, CMC (thin Client) for managing Users, security and Profiles 2) Oracle 9i includes Bulk Inserts, Index Rename and Table Rename. 3) SQL is a 4 GL (Generation Language). Pl/SQL is a 3 GL. 95. What is a Prompt? Prompts are used for asking the user for Dynamic Inputs while refreshing the Report. 96. Can we create reports without creating Universe? Yes we can create reports without creating Universe. 97. What are ad-hoc reports? Ad-hoc reports means with in the organization user can create reports by directly interact with IT peoples. That is time depended reports not detailed reports. 98. How to link one location universe to other location universe a) Click on File menu---> Parameter---> Links---->Add Link and then choose the universe you want to link and give ok. Then the universe is added to the existing one. b) In Designer, we can't join two universes, we can link two universes. 1. Click on the File menu; say Parameters then one dialogue box is displayed. 2. Click on the Links tab, and say Add Link then choose the universe u want to link and say ok. Then your universe is added to the existing one. 99. What is “maintaining universes”? a) Maintenance of universe means adding new tables, refreshing the table structure after adding new tables, create the joins between the new tables to existing tables identify loops if any,

examine the integrity checks after any changes, determining the cardinality if any, resolving the loops. Adding the new objects and classes, exporting, restricting access to users etc.. b) All the operations after the initial production phase are called maintenance of universe. We have to add some more tables to schema design as per client requirements and finding any errors after adding the tables. If at all any resolving them and generating reports. 10o. How to hide the tables in webi? We can hide a table in webI when the table is empty. From the properties tab, deselect 'Show when empty' check box. 101. How do u get requirement from the client? Design Specification (.doc) - Shows the architecture of the Project. Requirement Specification (.doc) - Security Requirements, Performance Requirements, Non Functional Requirements, Functional Requirements Project Plan (.mpp) - Project Duration Report Specification Template (.xls) - Look and feel of the Reports Data Element Matrix (.xls)- Tables and Columns involved in this Project. 102. How do u Receive requirements from the client? Through web intelligence and through browser 103. What is Scope of Analysis? a) Using this Scope of Analysis we know up to what extent we can drill the Report b) Scope of Analysis determines the additional objects to be included in the query so that the data will be available in drill mode. Before you can drill, you must use Scope of Analysis to select the objects to be retrieved in addition to those that were placed in the Result Objects. c) Scope of analysis: it let's u add more data to the micro cube from hierarchies. This data is used for multidimensional analysis. When you add the data to the micro cube, the added data is not initially displayed in the report. When you drill the data it displays the added data for the purpose of multidimensional analysis. The scope of analysis button is located in the query panel. Here we just specifying the path for objects to get the detailed or summarized information using drill option for analyzing the data in different ways 104. HOW TO EXPLAIN SHORT CUT JOIN AND THETA JOIN? a) Shortcut join: it is direct join between source and destination Example: country-->region-> city We can connect country and city using shortcut join Theta join: non equality condition between two tables. b) Short cut Join providing an alternative path between two tables. passing intermediate tables, leading to the same result, regardless of direction. Optimizes query time by cutting long join paths as short as possible. Theta join Link tables based on a relationship other than equality between two columns. 105. WHAT ARE THE TYPES OF UNIVERSES? PLZ EXPLAIN IT? Universes are two types 1) Simple Universe and 2) Complex Universe b) Derived Universe, Linked Universe and Core Universe are the Types of Universe. Simple and complex (linked universe)

106. What are the types of Connections? 1) Shared: Available to multiple users 2) Personal: Belongs to user, who created it, others cannot use it. 3) Secured: These are centralized and any one can use it and used to deploy business objects reports 107. What is meant by slowly changing dimensions? Master data occur in the OLTP system and that can't change regularly, when the changes are occurred in the OLTP system, that changes can be handled by the dimension tables. Such type of dimensions is called slowly changing dimensions. There are three types of dimensions TYPE1 (Maintain only current data) TYPE2 (Maintain complete historic data) TYPE3 (Maintain one time historic data) 108. What is meant by scorecards? Provide fast and effective way of monitoring key measures. Scorecard is a concept used for measuring a company's activities in terms of its vision and strategies, to give managers a comprehensive view of the performance of the business. 109. Case1: A person buy a car, case2: rent a car which is context & which is alias? Why? Buy a car is context & rent a car is alias Because, buy a car is a fact & rent a car is a look up, alias is created on look up tables. 110. What is meant by Ad hoc reports? Can any body will explain with examples. Ad hoc reporting is a user friendly feature designed for all levels of users. Custom reports are created using queries. b) Ad hoc meant for management users. Example BO is ad hoc reporting tool used to make quick decisions. Example: if you have a one shopping mall u want find out the stock status. For clearance of the stock u need to take a decision what type of decision u need to take for clearance of stock. 111. What is a Query? A query is one or more statements that request data from a database. If the data is available, then the requested data returns in the form of a table which contains rows and columns. Queries are sent to the databases in a language called SQL. However, when using the Report Panel, SQL knowledge is not required. 112. Explain about surrogate key? a) A surrogate key is an automatic system generated unique key. b) An artificial key which can be used to remove redundancy. c) Surrogate key is a system generated key which is defined at database level to avoid the duplication of records. it doesn‟t maintain any relations b/w tables like as primary key and it only allows unique data there is a command with sequence in oracle. d) A surrogate key is a substitution for the natural primary key. It is just a unique identifier for each row that can be used for the primary key to the table. e) Surrogate Key is unique identifier Key in Production System, to avoid data duplication and redundancy in DWH

f) In a current database, the surrogate key is the primary key, generated by the database management system and not derived from any application data in the database. The only significance of the surrogate key is to act as the primary key. 113. What is the difference between sub-query & co-related sub query? a) A sub query is executed once for the parent statement whereas the correlated sub query is executed once for each row of the parent query. Example Select deptno, ename, sal from emp a where sal = (select max(sal) from emp where deptno = a.deptno) order by deptno b) Nesting of queries, one within another is termed as a Sub-Query. 114. What is the necessity of oracle for business objects, why the interview panel is concentrating on oracle very much? Just we need the commands using select, joins? Why they r asking about cursors, triggers etc. What ever we do in the BO it needs to connect to Oracle with the help of queries. As my experience says, it‟s some times necessary to have the derived tables to be created which needs SQL knowledge, to do data validation we need SQL queries. Actually for any BO Developer optimum level of SQL knowledge is necessary. Because In BO we are mostly using oracle is as database. So what ever you are selecting in the query panel it is fired on the database in the form of query. All of us know it is done by designer automatically. But in some scenarios we have to implement freehand SQL queries, derived tables to get our target results and some times we have to validate the background SQL generated by BO to understand how results are coming in. And in creation of formulas and variables we need SQL knowledge. (to_char, to_date, trim, decode, sign, union, union all....). So SQL is must. Coming to the PL/SQL in some situations when the data is in huge amounts, normal sql not meet the required performance. So we have to use PL/SQL. So it is required in rare cases where you are uploading the data in the report automatically by running the UNIX batch or getting the huge amount of data in to the reports. As per my knowledge in real time it is better to know about the writing the procedures, creating the views are more enough. I think cursors, triggers etc are used depend upon data needs. 115. WHAT ARE TEMPLATES? EXPLAIN WHAT YOU HAVE CREATED? The different table templates you can use to display information on reports are: Vertical tables Horizontal tables Cross tabs Forms 1) Vertical tables display header cells at the top of the table and the corresponding data in columns. 2) Horizontal tables display header cells at the left of the table and the corresponding data in rows. 3) Cross tabs display values for dimensions across the top axis and on the left axis. The body displays the values of a measure that correspond to the cross section of the dimensions. 4) Forms are useful in your report if you want to display detailed information 116. WHAT IS CARTESIAN PRODUCT? a) It is a situation in which a Query includes two or more tables that r not linked by join. If we execute that query, it will retrieve all the possible combinations b/w tables that are not joined. In this situation condition is invalid or omitted completely, the result is Cartesian. c) A Cartesian product is defined as all possible combinations of rows in all tables.

d) A Cartesian product is a result set which contains all the possible combinations of each row in each table included in a query. A Cartesian product is almost always an incorrect result. 119. WHAT IS CARDINALITY? a) Cardinality is a property of a join that describes how many rows in one table match rows in another table. Cardinality is expressed as the minimum and maximum number of rows in a column at one end of a join that have matching rows in the column at the other end of the join. b) Cardinality defines the numeric relationships between occurrences of the entities on either end of the relationship line. Eg: 1)1:1 2)1: M 3) M: 1 4) M: M c) The minimum and the maximum number of row matches can be equal to 0, 1, or N. d) Cardinality is mentioning the relation ship between the two columns participating in a join... Eg: if cardinality is 1 to n...for every column value in first table's field there exists many column values for the field in second table. Ex: For every customer there may exists more than one address (Permanent and temporary) 120. HOW TO SAVE UNIVERSES AND DOCUMENTS IN THE REPOSITORY? a) When ever we save universe it directly gets saved in local repository. If we want to access these universe from deski or webi then we will have to save these universe to central repository by EXPORTING it, it will directly be saved in default location in central repository b) By exporting the universes and documents, we can save them to the repository. We can also publish them to the central repository. c) If u are working in client system u must save ur universe and files in server system repository. Process: 1st save the Universe. File-->export-->report conversation toolsok. 121. Can a Universe be linked to more than one data source? a) The Various data source are: Universe Personal data files Free hand SQL VB procedures Stored procedures OLAP servers b) Any number of data Source can be linked by linking common dimensions Features of Dimension: The dimension objects do not have to have the same name (E.g. Person, Person Name) Only dimension objects can be linked (e.g. Person Name, Encounter Type, etc.) The dimension objects must have a common data format (e.g. character, numeric, etc.) Common values must be in the same case etc. c) Yes, we can link to more than one data source. We can have universe connection to more than one data base. We can achieve this by creating the db link between two data bases and then connecting it to the universe to any of the db.

d) You can have a single database connection to a universe. e) Definitely it is not possible to use more than one database connection to a single universe. 122. IS IT POSSIBLE TO CREATE REPORTS FROM DIFFERENT UNIVERSES IN ONE DOCUMENT? Yes, it is possible to use different universe to generate a single report....multiple data providers. 123. TILL WHAT LEVEL OF SECURITY BO SUPPORTS? a) In BO XI R2, the row level and object level. Security can be done in the universe itself. b) In Bo the security levels are applied to row level and column level. Both have been handled by the administrator. In supervisor tool (or) in designer tool these two levels of securities are used to restrict the data at row level or column level in case of particular user or user group. 124. What is Row level Security? The measure of specifying user can retrieve which rows of data based on a column of data or combination of columns is called row level security. 125. HOW TO SPOT A HIERARCHY? From the designer u can spot the already mentioned hierarchy and also u can change or edit the same. Go to Tool->Hierarchies Here u can ether add a new one or can also edit the existing one. 126. WHAT ALL DIFFERENT KIND OF FUNCTIONS AVAILABLE WHILE DESIGNING UNIVERSES? Some other function like Number, Character, Date functions & @ functions like, @Aggregate_Aware, @prompt, @select, @where, @script and @variable. All the Universe Parameters (6 tabs) available in the universe parameters window are very important functions to create any universe. 126. WHAT TYPE OF JOINS RETURNS INCORRECT RESULTS? Isolated joins, cross join, non equi join 127. WHAT IS THE PURPOSE OF TESTING INTEGRITY OF THE UNIVERSE? a) To check the universe weather it is correct or in correct, means that any isolated joins, divergence, loops, contexts, wrong joins, parsing happened in the universe. b) An integrity check detects: 1. Invalid syntax 2. Loops 3. Isolated tables 4. Isolated joins 5. Loops with in contexts 6. Missing and Invalid cardinalities. 129. WHAT KIND OF TOOL BO Is? a) Bo is a reporting tool to Query the database or data warehouse. b) Bo is a query, reporting and analysis tool. c) Bo is an OLAP tool. (ROLAP) 130. HOW DO YOU RESOLVE MULTIVALUE AND COMPUTATIONERROS?

#MULTIVALUE error can be resolved by putting the input context. #COMPUTATION error can be resolved by puting the reset context in output context. Create a new variable(ex:test) and copy the formula of the old variable to this new one and assign the column to this new variable..is the solution for multivalue error. Computation error: Use Max() function before the formula in the report to resolve a computation error 131. HOW YOU WORKED WITH MULTIPLE DATA SOURCES?IF YES ?HOW DO YOU LINK THEM? you can create different universe for different sources and link them in BO. 132. HOW DO YOU SCHEDULE THE REPORTS? we schedule reports using broadcaste agent. we have a simple procees to shedule thee reports.when u saved ur report in perticular folder. connect sever through browser tool go to ur folders and shedule in 6.5 we can use broad cost agent but in the case of boxi we can use boe .net launch pad In 6.x and previous versions, Broadcast Agent is used to schedule the reports. In XI and XI Release 2, any user who is authorised to schedule documents can schedule the reports. Broadcast Agent lets any authorized user schedule documents to be refreshed on a regular basis. Scheduled documents may then be automatically distributed to targeted individuals or groups or published for all users to access. Users can customize the information they send by executing a standard report and then bursting it so that recipients receive only the information they are entitled to by their security profile. 133. GENARALLY WHAT ARE THE PROBLEMS ARE FACING WHILE CREATING REPORTS? THE MOST COMMON PROBLEM IS JOIN PATH PROBLEM i.e, LOOPS CHASAM TRAPS FAN TRAPS 134. GENARALLY HOW MANY UNIVERSES ARE CREATE FOR EACH PROJECTS? It's depends on the project requirement. There is no restriction on the creation of the universes. It's all depends on the project In general, One universe is sufficient for a project and if we need we can link other universe from other projects...

this totally depend upon ur project requirement 135. i am using Business Objects 6.1(a) facing a problem. ie when we save report in xls format then in xls sheet pictures are inserted into rep file are not come. Is it a bug. we can't save the report with chart in xls,text format. only save in html,.rep,pdf While saveing the report we have to save in the form of save as select this format:- 1)Microsoft Excel Sheet(.xls) 2)HTML format(.htm) 3).pdf you can select any one of them it is possible. 136. Re: what is the diff between etl tool and olap tool ETL tool is used to extract, Load and Transform the data from one system to another system. OLAP tool is a reporting tool which will generates the reports that are useful for dicison support for top level management ETL tool are nothing but OLTP tool whereas OLAP tools are report net tools ETL(OLTP) are extracters tranfers and loaders type OLAP tools are analysers 137. WHERE DO YOU USE GLOBAL FILTERS ,EXPLAIN WITH EXAMPLE? gobal filter acts on all fields in the report table 138. WHAT PROBLEMS ARE NOT KNOWN WHILE PERFORMING INTEGRITY CHECK? We can't find traps i.e. chasm trap and fan trap. It can be identified only by visualization. 139. CAN A REPOSITORY CONTAINS REPORTS? yes repository contains reports in bo 6.5 reports are stored as documents in repostory in bo xi reports are stored as folders in cmc Yes, Repository contains reports. In BOXI also reports are stored in repository (file repository). Those reports in folders are also stored in repository only. Yes, Repository contains reports. In BOXI also reports are stored in repository (file repository). Those reports in folders are also stored in repository only. bo 6.5 rep contains 50 tables........ bo xir2 contains 8 tables..... 1 table is dedicated for documents(document domain).

these 8 tables r also called cms db(central management server)........ Repository Database will not store the actuall report file, it has the pointer of the report. Yes, Repository contains reports. In BOXI also reports are stored in repository (file repository). we can save our reports in folders(phsycal) and categories(logical)..these are avilable only repository only 140. WHO ARE THE USERS OF THE REPOSITORY? general supervisor creates repository and designer ,user (report devlepoer ) uses the repository...the documents are stored in document domain...in fact the clients also uses the repository while seeing the documents General Supervisor, Supervisor are the users of the repository. Since they are the owners of the repository they can create the repository and modify it whenever they want. who is having user as well as admin rights to access the repository 141. IF I WANT TO INSTALL BO ENTERPRISE PRODUCTS IN WINDOWS 2000 PROFESSIONAL SERVER, WHAT SHOULD BE THE SYSTEM CONFIGURATION? • P3 700MHz** • 1 GB RAM • 5 GB hard disk space for BusinessObjects Enterprise and 1.5 GB additional for Performance Management • CD-ROM ** Windows support is limited strictly to the 32-bit versions of Windows operating on either 32 or 64-bit (x86) AMD/Intel chipsets. BusinessObjects Enterprise software for Windows is not warranted or supported for use on other chipsets. 142. User name and password is saved by Business objects when we create repository. and this username and password is saved in Table obj_m_actor table in repository. The password in incrypted form. It is possible to Dycrypt That Password. Not possible. 143. Can we edit BOMain.Key file to connect with other repository with same supervisor user name and password. But Database is different. Yes 144. How you get the requirement from client? client gets the information. that information is not in the order.they r unable to under stand info.it can not helpfull to take the decessions. then the clint meets the company. Clent first contacts the company's Business DevelopmentManager of the company, Then Meeting and a chat happens in a clients place or client coming to company, Then gets the requiement according to the deal 144. what is prompt? Cascading prompt? Syntax

To prompt the values and it is used on where condtion and filter row syntax @select(class\object )= @prompt ('message','type','{values1,values2...},class\object,mono\mu lti,free\constrained) it is nothin but a dialog box it can used for to take the values. syntax: @prompt('message',['type'],[lov],[mono/multi],[free/constraint]) Prompt: It is used to create an interactive object. and also it is dynamic filter. General syntax:@prompt('message',['type'],[lov], [mono/multi],[free/constraint]) In designer we can write this way, @select(class\object )= @prompt ('message','type','{values1,values2...},class\object,mono\mu lti,free\constrained)). Cascading Prompt: it is based on one prompt to another prompt. it is also refer to hirerchy also & designed in uni level. IN BOXIR2 wise:-- go tools --> click cascading lov --> edit lov window open --> write conditions how many prompts u want. --> click ok. 145. what is drill down? Action of navagating thorough levels of data. by drill down youn can reach the more refined or detailed information. analysing the data in different angles and levels Drill down is a one of the concept in Drill. Drill is nothing but an action of navigating data thru levels of data. Drill down - with the use of drill down you can reach more detailed information. Navigating data to lower level in the hierarchy with in the cube move from summary information to detailed data.Drilling the data into end level of hierarchy 146. what is slice & dice? slice and dice is to arrange the the data in differnt ways. it can chage as rows to columns and columns to rows. The ability to move between different combinations of

dimensions when viewing data with an OLAP browser. Multidimensional analysis tools organize the data in two primary ways: in multiple dimensions and in hierarchies. Slicing and dicing refers to the ability to combine and re- combine the dimensions to see different slices of the information. Picture slicing a three-dimensional cube of information, in order to see what values are contained in the middle layer. Slicing and dicing a cube allows an end- user to do the same thing with multiple dimensions. 147. what are the features in BO? define scope of analysis. define condiations. create master and detail reports. add formulas,local variables and functions breakeup tables and disply tha calculations. create charts. analyze the data in drill mode. use slice and dice. formate reports. export reports. most of the reporting tool had same features but bO is more secure..can work with remotely using web I,with out installing of BO s/w in ur local system 148. Why we are going to data warehouse? Data warehouse is used for to store the large volumes of data. It can be used for future forecasting. It is the collection of key pieces of information that can be used for to take the decision by the managers. The main aim of data warehouse is in analyzing the large volumes of data so that it can be helpful in taking business decisions for reporting one day details also enough.but analysis means we need comparision means we need some old data is called historical data.the data ware house saves historical data ,we con't to any data base manuplations. where is in normal databases we arte able to maintain some extent of data .after that for entering new data u need to delete the old data. BUT in Data ware house u are able to stote years of records no need to delete the old data 149. what are the multidimensional analyses multidimensional analyses that can be used to wide view varities of data or information Multidimensional analysis is the analysis of dimension objects organized in meaningful hierarchies. A hierarchy is an ordered series of related dimensions. Multidimensional analysis allows you to observe data from

various viewpoints. Multidimensional analysis means analysing the data by looking at various view points. In BO,In 2 ways we can do this.1.Slice and Dice 2.Drilling. Multidimensional analysis is analyzing the data in different ways. There are two options are available in BO, 1.Slice and Dice, it allows us to view data differently i.e. we can change the position of the rows to columns and columns to rows. 2.Drilling, using drilling option we can view data in different views i.e. we can know the level details of any dimension. Suppose if we take Date dimension, we can use drill option to view the next level of detail i.e. from year to quarter and from quarter to month and from month to day. 150. What is data mart? datamart is nothing but a database. it can be stored data about the particular orginazation. A data mart is a particular subject oriented block of data in the datawarehouse in the business line like production, sales, marketing etc. they are two kinds of datamarts are there one is independent & Dependent datamarts. sub set of datawarehouse is called data mart. A data mart is a subset of data warehouse that is designed for a particular line of business such as sales, marketing, finance, etc. Data mart is of two types: 1) Dependent data mart, in which data can be derived from an enterprise-wide data warehouse. 2) Independent data mart, in which data can be collected directly from sources. In the industry when a organisation goes for a enterprise wide Datawarehouse the cost involved in setting up . its maintenance and other overheads are also associated with it. So due to budget and time constraints some organisations initially set up a Data Mart to facililtate there immediate needs . These Data Marts are generally set up at department levels and in a future date if utility arises then datamarts across the organisation can be integrated and a full fledged data warehouse can be formed. In a way Data Mart is a subset of Data Warehouse. 151. .what is conformed dimension? R u used? Confirmed Dimention is a dimention table which is connected to the multiple fact tables A dimension that is used in more than one cube. The use of conformed dimensions and shared measures is the

primary way a set of data marts can be united into one consolidated data warehouse. conformed dimension table is once created that is not changed occutionally A Confirmed Dimension (CD) is a dimension which is shared by different fact tables. it is a dimention accept ble join relation between two facts 152. what is LOV? where it is store? LOV is the list of values.it can retrive the data values associated with the particular object. this can be stored in sub folder of USERDOCS with .lov extension. LoV is list of values it displays the list that contains the data values associated with an object. A list of value can contain data from two types of data sources... 1. Database file 2. An External file. LOV is nothing but listy of values. as per require ment we can generate LOV for limited no of objects.we can save it in repository server we have cascadiding loV SALSO WE CAN GENERATE LOV S FOR MULTIBLE OBJECTS AT A TIME 153. What is repository? Types In XIR2 CMS Repository :Which consist of two database (System & Audit)Input file repository: Template of the report Output file repository: Instance of the report. repository is the set of data structers that can be stored in the database. repository is a oraganizing metadata or cenralizedmetadata storage place reposirory is create new folder structure types: repository manager repository admin console repository is a central store area between group of users.repository is avilable under cms input and output repositories 154. what is alias?

one user prefrom different roles is called alias eg two dept are there sales , HR user of sales working in HR with different row is called alias. alias is logical popint to alternate to the table name.this can be used to resolve the loops. Aliases are references to existing tables in a schema. An Alias is a table that is an exact duplicate of the original table with a different name. The data in the table is exactly the same as the original table. An alias breaks a loop by using the same table twice in the same query for a different purpose. An alias is a logical pointer to an alternate table name. Exact copy of the original table.Establish a one-one join between the original table and the table which is aliased. The aggregatre results should be canned on to the aliased table and not the original table. alias is a logical table of existing look up table.using alias we can resolve looops 155. What is loop? How resolve the loop?explain it? a situation occures more than one path exists from one table to another table. to reslove the loops we can use the allias ans context. if a loop contains only one lookup table then the loop can be resolved by detecting the alias. if a loop is having 2 or more fact tables(multiple fact tables) then the loop can be resolved by detecting context. Loop can be resolved either alias/ context. Loop is a Multiple paths between the tables selected in queries. Or you can say loop is a closed path structure. Loops can be resolved by… ALIASES •Alias - Same as the namesake in SQL. •Exact duplicate of the original table. .A different name “tricks” the SQL query to accept that you are using 2 different tables. CONTEXTS •Rule which helps BO decide which of the 2 paths to choose in a loop. •BO prompts the user to indicate the correct perspective (relevant path) for the query. When to Alias A loop with a single lookup table should be resolved by an alias A lookup table can be identified by its cardinality A lookup table only has the „one‟ end of joins attached to it If your universe is simple in terms of tables then go for

alias. If your universe is complex in terms of tables then go for Context. Alias entails the propogation of the universe. Contexts are not liked by the enduser because we are forcing the enduser to the database which is the against to the universe basic rule ie to keep the endusers away from the database. loop is nothing but a continuous data flow .it is a pipe line.it is a close path end to end..using alias table we can resolve loop s A loop is a set of joins that defines a closed path through a set of tables in a schema. Loops occur when joins form multiple paths between lookup tables. 156. what is context? How u create? With example. it is a set of joins that specefies one of several paths through tables in loop. if a loop is having 2 or more fact tables(multiple fact tables) then the loop can be resolved by detecting context tools-->insert context then you can select the path. 157. How can we improve performance? By making use of Aggregate tables. 1)usinf aggregated tables 2)using shortcut joins 3)removing unwanted classes and objects 4)removing unwanted joins 5)lov should be based on smaller look up tables 158. What is the use of BO SDK? Bo SDK main use is to suppress ?no data to fetch? using Macros. The BusinessObjects Enterprise SDK allows you to build web applications that interface directly with your BusinessObjects Enterprise system. BO SBK Means, BO Software Development Kit. It Used for BO With Java or BO With Dot Net Integration. You can integrate BO in java or .Net application. It provide Java & .Net Api classes & functions. 159. What are the general issues in migration process? Alignment, performance. Before Migration, one should have a thorough with 1. Import Wizard 2. Report Conversion Tool - for converting the DeskI Reports to WebI Reports

Issues can be: 1. What type of Migration u want to Use- a) Single Pass b) Incremental Migration 2. Importing Security or not. 3. Repository Migartion- such as a) Merging Multiple repository into one b) Moving one to Multiple Repository (Depends on the requirement) 4. Need to take care of Versions and Platforms - Supported databases,Web and Application Servers, Web Browsers and Operating Systems. 5. User/Group Migration 6. Setting up Folders/Groups Structures. 7. Document Migartion. 8. Taking Backups 9. Setting Up Servers etc. There are lot other issues also. 1)Formatting issues 1)Linking Universes 1)hiding of variables you cant do it in xi r2 160. Why do we need metrics and sets? Metrics are used for analysis and Sets are used for grouping. 161. what is the source for metrics? measure objects. 162. What is the use of AFD? Where it can be stored? used to create dashboards. It can be stored in repository, corporate or personal. 163. What is a Set? Its nothing but grouping of users. 164. What is metrics? Metrics are a system of parameters or ways of quantitative and periodic assessment of a process that is to be measured. These are used to track trends, productivity. 165. What is the difference between master-detail and Breaks? In break common fields are deleted whereas in master- detail , we declare certain entity as a master to get the detailed information or report in this case the table format is changed. In Section(Master Detail) you can have two or more different crosstabs or tables(hori/fin) eg. orders, customer, products etc Where as In break one block is break into groups and subtotal is shown eg customer can be broken into country/state/city

In Section(Master Detail) you can have charts for each section or detail. can have chart and table combination as well. Whereas in Breaks u cannot inseart a chart for each of the groups formed out of break 166. What are Alerter, Filters, Breaks and Conditions? Alters are nothing but they are used to draw attention to a block of data by highlighting. Breaks are nothing but grouping the data without any change in the format. Condition is used to retrieve data which meets certain criteria. Filters are used to get necessary data. Alterters are conditional tests. Conditions restict the data at the database level. Filters restrict the data at the report level. Breaks can be used to remove redundat data and the data remains with in the cell content. 167. What is a join? Explain different types of joins? Join is used to link to tables depending upon the data requested by the user, Usually we have Inner Join, Outer Join, Left Join, Right Join, Full Outer join. Combining a data from multiple tables is called join. There r 5 types of joins r there. 1)Simple join 2)Equi join 3)Outer join 4)Theta join 5)Short cut join A join is a condition that links the data in seperate but related tables. The tables usually have a parent-child relationship. If a query does not contain a join, the database returns a result set that contains all possible combinations of the rows in the query tables. Types of joins: 1) Equi-Joins Link tables based on the equality between the values in the column of one table and the values in the column of another. 2) Theta Joins Link tables based on a relationship other than equality between two columns. 3) Outer Joins (Left Outer, Right Outer, Full Outer) Link two tables, one of which has rows that do not match those in the common column of the other table. 4) Shortcut Joins Join providing an alternative path between two tables, bypassing intermediate tables, leading to the same result, regardless of direction. Optimizes query time by cutting long join paths as short as possible.

5) Self restricting joins Single table join used to set a restriction on the table. join is very imp concept in BO relation between two tables is called joins. we have 4 types of join relations 1:m,m:1,m:m,1:1 types of joins in BO 1)equi join 2)theta join 3)outer join(left/right) 4)isolated join 5)short cut join 168. What is a loop? How can we overcome? loop is a closed path between end to end.continuous floe of data.creation of alias table is solution to resolve loops Loop is nothing but a closed circular flow; it can be overcome by making use of Alias and Context. A loop is a set of joins that defines a closed path through a set of tables in a schema. Loops occur when joins form multiple paths between lookup tables. Loops can be solved by using aliases or contexts. loop is a closed path between end to end.continuous floe of data.creation of alias table is solution to resolve loops 169. What is the size of data base? In general it will be anything between 4-8 Terabytes. 170. What do you mean by Object qualification? Object qualification represents what kind of object is that, usually we have three types of object qualifiers they are measure, dimension, detailed. Object qualification is nothing but a property of an object determines how it can be used in multidimensional analysis. For the purpose of multidimensional analysis objects can be qualified as dimension, detailed and measure 171. What is a category? we can store logical report here.in real time we can use categories only.we can't manuplate the categories report It is nothing but grouping of certain entities. Categories tag objects in a meaningful way to provide an additional method of classification, which makes searching for content easier for users. A Report in one Folder may assigned to several Categories. Types of Categories:

1)Corporate Categories – Created by admin or users who has admin rights. 2)Personal Categories – Created by each user to organize their own personal documents. 172. How do you restrict access to rows of a database? In XI version it can be done by using row-level security in designer module whereas in 5i/6i it is done by supervisor. 173. Can we have multiple domains? Yes. we have multiple domains,but security domain is not multiple,only document domain and universe domain is multiple. 174. When is the Repository created? In 5i/6i versions after installing the software, whereas in Xi version a repository is created at the time of installation. 175. What is domain? How many are there in a basic setup? What are they? Domain is nothing but logical grouping of system tables, There are three domains usually in a basic setup, They are Secure, Universe, Document. Business objects are sometimes called domain objects , and a domain model represents the set of domain objects and the relationships between them. 176. What is BO Main. Key? BoMain.Key file contains the information about the repository site i.e it contains the address of the repository security domain. The General supervisor username n password is stored in bomain.key file BOMain.key file contains the address of the repository's security domain. This key file should be distributed to all the users of BO to work with BO or will access the bo repository to share universes and documents. It is stored in BusinessObjects/LOCData folder. 177. How to create Generic TIME CLASS, which includes Objects Year,Month and Qtr? year=to_date(to_char(timeclass,'yyyy')); month-->to_date(to_char(timeclass,'month')); 178. How to link two different universes ? go to universe parameters and select link tab and then select the universe. Universes can be linked using Universe Parameters. You can link universes with any of the following approaches: 1)Kernel approach 2)Master approach 3)Component approach

With the Kernel approach, one universe contains the core components. The derived universes that you create from this kernel universe contain these core components as well as their own specific components. Any changes you make to the kernel universe are automatically reflected in the core components of all the derived universes. The Master approach is another way of organizing the common components of linked universes. The master universe holds all possible components. In the universes derived from the master, certain components are hidden depending on their relevance to the target users of the derived universe. The components visible in the derived universes are always a subset of the master universe. There are no new components added specific to the derived universe. Any changes you make to the master universe are automatically reflected in the core components of all the derived universes. The Component approach is merging two or more universes into one universe. we have a concept in BO linked universe there we can klink multiple universes. file--.parameters-->links 179. How to Implement the the Built-in Strategy Script in BO Designer? strategy is used to extract structural information about the tables, joins ... bo has 2 strategy 1. built-in -strategy 2. external- strategy 180. What are the security level used in BO? they r four 1.hidden 2.disable 3.inhernt 4.enable Security Levels in BO XI are: 1) Predefined 2) Advanced Predifined: 1) No Access 2) View 3) Schedule 4) View on Demand 5) Full control With Advanced you can explicitly define the security level. 181. What is slicing and dicing in business objects? slice & dice is used to analyse the data in different views & perspectives

Slice and Dice can be applied to rotate a microcube in order to view it from different perspectives. A microcube is a conceptual way to present the data returned by a query before it is projected onto a report. You can choose all, or only some of the data held in the microcube to create a report. slicing means it slices the cube based on a dimension dicing means rotates the cube with independent of dimension 182. How will you know the version of Bo using designer? in designe select the file tab,then click on parameter tab in that select summary tab then we will get the information by emam While opening the designer,a BO patents page appear which shows the version of BO 183. Which command using Query Analyzer will give you the version of SQL server and operating system ? select @@version 184. How can we acheive Correlated sub-query in Designer? A correlated subquery is a SELECT statement nested inside another T-SQL statement, which contains a reference to one or more columns in the outer query. Therefore, the correlated subquery can be said to be dependent on the outer query. This is the main difference between a correlated subquery and just a plain subquery. A plain subquery is not dependent on the outer query, can be run independently of the outer query, and will return a result set. A correlated subquery, since it is dependent on the outer query will return a syntax errors if it is run by itself. 185. Explain in Detail about Measure Objects? and what is the use of it? How to create it? It can be derived fro the Aggregate function.it convay the numeric information by Dimesion object can be measured. Measure objects retrieve numeric data, or data that is the result of calculations on data in the database. For example: No. of students in the Students Universe. Measure Object convey numeric information which is used to quantify a dimension object. A measure object returns numeric information. You can create a measure object by using aggregate functions such as, 1)Sum 2)Count 3)Average 4)Minimum 5)Maximum

Measure objects retrieve numeric data, or data that is the result of calculations on data in the database. For example: No. of students in the Students Universe. It can be derived fro the Aggregate function.it convay the numeric information by Dimesion object can be meassured 186. What is the local filter and global filter in bo's? To hide & display the data. Local Filter is to single block to which it is created, but a global filter is to all the blocks which consists of that column a report can contain more than one block...same way a document can contain more than one report..... so if we see one report we have some blocks.... applying a report filter to only one block is local filter.. applying a report filter to all blocks is global filter... in any report. Global Filter will affect whole Report But local filter will affect selected both only. 187. What are the steps to taken care to improve the Report performance? The Report Performance can be improved by the following performance Requirements : 1- The Report should open within 10-15 Minutes 2- The data should be available within 24 hours For Example - If there is some data error , it has to be taken in ETL ( Extraction , Transformation , Loading ). When the mapping got refreshed , the data should be fetched into the Reports within 24 hours As part of universe parameters increase the array fetch size and try to use aggregate awareness. 188. How toconnect one to one report? You can link thru Hyperlink option By using drill down functionality additional components will be added in HTML Tag. 189. What is the drill up , drill down, drill by , drill trough ? drill-down means analysing the in different levels going to the down let us eg as year--->quarter,quarte---> month and so on drill-up means analysing the in different levels going to the up let us eg as month--->quarter,quarte---> year and so on 190. How to create Universe using Flat file in BO6.0 If i am not wrong u can't create universe from a flat file but u can generate a report from a flat file. choose "personal data files" in the new report wizard instead of univese and input the file information.

191. What is the test methodology for testing BO Universes? Integrity Check is the option through which one can test the universse in BO. 192. How can you access your repository with different user profiles? first thing we are under the member(user) of the repository.and we need to rights to access repository. we also need to create perticular user name and pass 193. What is pragma? A PRAGMA statement appears in a PL/SQL block. It is not an executable statement, but it provides instructions to the compiler 194. Can we take report on Excel in Business Objects? yes. The businessobjects separately provided the option of get the report data from universe or others(personal data option)in the business objects entered wizard. Click or Select the others option and it will let u different files or extension files. here select .xls file and follow normal report style. Yes, When u get the output of report then use save as .XLS option. s sure,when we save the perticular report we have a option to save in .XLs Yes, We can take a report on excel in Business Objects, Process .... In Desktop Intelligence -> File -> New - Generate a standard report -> Begin -> Other -> Personal Data Files -> Finish -> format -> xls & select excel file from browse option -> If excel file first row contains column name then select the check box -> First row contains column names -> Run. ------------------------------------------------------------ If you want to save a BO report in excel format then, After generating a report file -> save -> File name - > ....... & save as type -> xls -> Save 195. What is batch processing in Business Objects? batch processing means scheduling the reports 196. What are different types of saving options in web intelligence? we can save as excel, RTF and .rep PDF and html also The saving formats with web intelligence are excel, pdf, csv and csv with options. Not possible with rtf, rep and html.

The saving options with webi are: 1) excel 2) pdf 3) csv 4) csv with options (Not possible with rtf, rep and html) we can see save the report as excel...webi....adobe acrobat....thats all ...no rep... rtf...etc. we can save webintelligence documents in two ways 1.excel 2.pdf only 197. What are alertors in Business Objects? Alerts are set of instructions and rules to highlight output of reports. Alerters are conditional tests which can be used to highlight the critical data. we can apply a maximum of 10 alerters on a single dimension/column and a max of 30 alerters on a report. 198. What services the broadcast agent offers on the server side? We can monitor the Scheduled Reports are controlled in the server side. We can resume or cancel the reports running in the Broad cast Agent. 199. In Business Objects 4.1 version what is the alternative name for broadcast agent? Document agent server 200. What are steps to be taken care to create a good Universe? A Universe is a business-oriented mapping of the data structure found in databases: tables, columns, joins, etc. A Universe is a semantic layer between Database and end users. A Universe can represent any specific application, system, or group of users. For example, a universe can relate to a department in a company such as marketing or accounting. A Universe can also pertain to a section within a department or just about any set of organized procedures such as a payroll or inventory system. A Universe consists of a set of objects, grouped by classes. Steps to be taken care to create : Prepare : Know the data source Analyze :Identify the needs of the end user population Plan : Design the universe(s) Implement : Create the universe(s)

Test : Using a test team (including end users) Deploy : Distribute the universe to end users Evolve : Adapt and extend universe over time 201. What is broad cast agent? Broad Cast Agent used to shedule or refresh the document on particular period of time(day, weak, month , etc) and also send those documents to the users. BCA is used to publish or refresh the documents in regular intervals i.e Broadly speaking BCA is used to schedule the documents. BCA is used to schedule the documents and also used to send the documents to users in pdf & excel format. BCA is used to schedule the documents. Using BCA we can send the documents to users in pdf & excel format. bca is avilable only in 6.5 when we work with XI R2 we have publishing wizard .through this we can publish our reports unders repository 202. Where will you find the address of repository in Business Objects? You can find if from .key file BOMain.Key BOMAIN.KEY it is located in LOCDATA folder 203. What is security domain in Business Objects? Security domain checks the users & their previlages There are there domains in BO, 1. Security Domain 2. Universe Domain 3. Document Domain Security Domain : It contains all user name & Password.Like it ll hold all the User credential informayion Universe Domain: It hold all the Universe Information Document Domain: Nothins but Report Information to check the user previlages ,means authentications Security domain is created with 25 metadata tables, which contains the user name and password of all the users,who enable the repository access. Business object supervisor product performs a database authentication in business object. With in the business object repository we can have only one security domain.

204. Types of universes in business objects? universe types in BO is secured shared personal This is not Universe types. Personal,Shared, Secured are Unverse connections. most prefered Secured , we can export all changes made in unverse. where as other connection does not allow. two types of universe are there 1) Simple 2) Complex There are two types of Universes 1.Ad_hoc Universe . 2.Non Ad_hoc Universe . There are two types of categories personel(Non Ad_hoc)& Corporate(ad_hoc), The two types of universes are kernel univers and another is derived universe. I think this is the correct answer. these question is not specific ....there may be many situations in bo where we can classify the universes.. i'll tell some..... 1.depending on type of data universe objects mapping adhoc (corporate data) non adhoc(personal data) 2.in linking universes scenario core universe(called kernel or master universe) and derived universe 3.depending on universe parameters. secured universe..personal universe...shared universe.. simple and linked 205. What are universe parameters? universe parameters are universe name which is given by the designer and connection to database source. so they are universe name database source. Universe Parameters Definition Name: Enrollment - Registrar only Description: Views of student enrollment data. Includes course information since 1995 a nd is retained for up to 5 years. Updated nightly. Connection: DB2 Secured

Who launches the supervisor product in Business Objects for first time? general supervisor 207. Analysis in business objects? Analysis in BO is Utility in BO with the help of that we can manage our document.. Anlysis in BO with the help we can Slide, Dice and Drill the reports Anlysis in BO with the help we can Slide, Dice and Drill the reports

208. can BO generate reports with out CUBICAL data to repository? In BO the cubic structre cannot be perfomed it's not supported for building the cubicstructure where as the cognos will support. i hope this is the usefull answere.. No!! Business Objects can create the reports without Cubical data also. Ex: In the Fullclient application of BO we can create the report based on the excel sheet. Just create the excel sheet having two rows and select the dataprovider as the Excel sheet and Run it, You will get the BO report. That means you are not having the CUBICAL DATA at the souce, even though you can generate BO reports. 209. what is main functional differences between BO and COGNOs? BO : Business objects, objects in object-oriented programming meant to represent business entities. Business Objects, a company that creates and markets business intelligence applications analyzing internal and external data. COGNOS : which makes business intelligence (BI) and performance planning software. Business Objects 1.BO -- ROLAP Reporting Tool. 2. It does not support MOLAP cubes. Cognos : 1. MOLAP Reporting Tool. 2. u can create CUBE based on Business Req 3. Develop reports both ROLAP and MOLAP BO->for management users adhoc reporting cognose-->for production users-.standered reporting 210. how to test reports in businessobjects? if we are using oracle as a data source we can use TODD (fornt end for oracle) to test the report . Take the SQL statement from the SQL editor of Query panel and run the query in the Todd . In BO intially to check the report, we go for Integrity check . One button is there to check the integrity,parse error, joins,loops and soon. The second stage of testing involves testing the SQL query of the report if it uses free hand SQL else we need to test the universe which the report is using.

If we use the query of the report in the TOAD it would show the same result. And the integrity check is only for testing the universe and not for the report. We would check the report by manually. As the report having n number of rows we would not check for all and check it randomly. This is the way to test the report. To test the report the simply write the SQL query and test it in the database, if copy and paste the SQL generated by the BO in Report Panel and fires it in TODD then it gives the same result. So to test report we need to manually write the SQL and then test it in the database and compare whether the result is correct or not. For your kind information, Integrity Check is not used for Universe testing and not for Report testing. 211. What is a Universe? Universe is semantic layer between data base and query panel. A universe is a file that contains the following: • Connection parameters for one or more database middleware. • SQL structures called objects that map to actual SQL structures in the database such as columns, tables, and database functions. Objects are grouped into classes. Objects and classes are both visible to Web Intelligence users. • A schema of the tables and joins used in the database. Objects are built from the database structures that you include in your schema. The schema is only available to Designer users. It is not visible to Web Intelligence and Desktop Intelligence users. A Universe is a business-oriented mapping of the data structure found in databases: tables, columns, joins, etc. A Universe is a semantic layer between Database and end users. A Universe can represent any specific application, system, or group of users. For example, a universe can relate to a department in a company such as marketing or accounting. A Universe can also pertain to a section within a department or just about any set of organized procedures such as a payroll or inventory system. A Universe consists of a set of objects, grouped by classes A universe is a semantic layer which isolates the end user from technical issues of database structure. Actually it is a file which contains the connection parameters to database middleware. It contains the structures that map to actual SQL structures in the database like columns, tables. A schema of tables and joins used inthe database.

Universe is a semantic layer that maps the data structure found in databases(tables,columns,etc)in business terms. A universe is a file that contains the following: 1.Connection parameters for one or more database middleware. 2.SQL structures called objects that map to actual SQL structures in the database such as columns, tables, and database functions. Objects are grouped into classes. Objects and classes are both visible to Web Intelligence users. 3.A schema of the tables and joins used in the database. Objects are built from the database structures that you include in your schema. The schema is only available to Designer users. It is not visible to Web Intelligence and Desktop Intelligence users. 212. how will u create a report using oracle stored procedure? u need to create a stored procedure using in/out parameter of a ref cursor. the parameter of the proc should be in only. then create a connection to the database using middleware. suppose u have created a proc on oracle 9i, then make the connection using oracle client.mention the user name/password and the data base name in the connection. then in the report section use the stored procedure as data provider and select the proc using which you want data ang generate the report. this is a sample one create or replace procedure proc_name(proc_cur in out sys_refcursor) as begin open proc_cur for select * from tab; end; follow his steps for Creating report using SP: 1-Select Data---New Data Provider--Stored Procedure 2-Select or define the db connection 3-Choose the stored procedure 4-Specify stored procedure as the data source 5-Define parameters Use REF CURSOR with IN/OUT parameter. Ref cursor is a cursor variable that points to any cursor, mainly used for returning the CURSOR OUTPUT. Eg: CREATE OR REPLACE PROCEDURE BO_proc(proc_cur IN OUT sys_refcursor) AS BEGIN OPEN proc_cur FOR SELECT * FROM EMP; END;

213. In BO module, you forgot all password even all user in business object, designer, supervisor, general supervisor everything, how to you recover your details? You can change supervisor password first using below steps and then change all the users passwords using supervisor. Warning: Direct manipulation of the repository tables can cause damage to your repository and will void your support contract. Do so at your own risk. If you don't have a second general supervisor, you could try the following SQL run against the security domain database: Code: Update OBJ_M_ACTOR Set M_ACTOR_C_PASSWORD = NULL Where M_ACTOR_C_NAME = <username of general supervisor>; This will set the password for the general supervisor to null, and therefore the next time you login, you will not need to enter a password. It is recommended that a password is given as soon as possible via the supervisor module. You will also have to set the status of the user login; otherwise even with a null password Bo will not let you log in. The status column is in OBJ_M_ACTOR and is called M_ACTOR_N_STATUS. If you set this flag to 1 along with setting the password to null then you should be okay. If this still doesn't work, make sure you have committed the database update 214. How to create derived Tables in BO 6.5 with columns from different tables in the universe and how it has to be joined in the universe? I have no idea about BO6.5 however I feel that creating Derived table must be similar in both XIR2 and BO6.5. -right click any where in Designer. -select Derived table from Popup menu. -A window will open up. Give the name of the derived table, You can specify the SQL stmt here as you do in oracle(if you are using oracle DB). Example: Select BONUS.ENAME Ename, DEPT.DEPTNO, EMP.EMPNO from Bonus, dept, emp where EMP.DEPTNO=DEPT.DEPTNO You can specify the join in SQL stmt if necessary. However joining the Derived table indeed is similar as joining a normal table. 215. How do u implement dense rank in bo reports? Dense Rank is used for assigning a precedence or rank to each row in the result set relative to other rows in the result set. The DENSE_RANK function computes the rank of a row in an ordered group of rows. Rows with equal values for the ranking criteria receive the same rank. Eg :-To Show the set of sales people who make the top 3 salaries - that is, find the set of distinct salary amounts, sort them, take the largest three, and give me everyone who makes one of those values. SELECT * FROM ( SELECT deptno, ename, sal, DENSE_RANK() OVER ( PARTITION BY deptno ORDER BY sal desc

) TopN FROM emp ) WHERE TopN <= 3 ORDER BY deptno, sal DESC / DEPTNO ENAME SAL TOPN ---------- ---------- ---------- ---------- 10 KING 5000 1 CLARK 2450 2 MILLER 1300 3 TT 3000 1 <--- ! (in case of rank JONES will have 3 and dense rank will have 2) FORD 3000 1 <--- ! JONES 2975 2 ADAMS 1100 3 30 BLAKE 2850 1 ALLEN 1600 2 30 TURNER 1500 3 216. What is aggregate navigation? Aggregate Navigation is used to specify the incompatible objects. Whenever we use Aggregate Aware we need to set up in compatibilities to work it properly (so Business Objects knows what SQL to generate) For example, there are 2 aggregate tables fact table by week and by day. If you set up a measure as aggregate aware from both tables - total quantity for example, the select might be something like: - Aggregate_Aware(sum(week_agg.qty),sum(day_agg.qty)) The week table listed first as this would be the preference. But as Business Objects needs a reason to not go to the week_agg table, this is done using incompatibilities. For example the Week Number dimension object would be compatible with the week_agg table as it will link to it and the data is held at an appropriate level to report against it. However the Date dimension object would be set as incompatible with the week_agg table, such that when it is selected alongside the Quantity object, BusinessObjects knows to jump to the next option in its select definition. 217.
