SAP BO Designer

Business Objects Designer is a SAP software tool that allows developers to createUniverses for Web Intelligence and Desktop Intelligence users It is a client application!accessible after the installation

What is a SAP BO Universe,

SAP BO Universe is a se$antic la#er that isolates end users fro$ underl#ing databaseor technical issues of database A universe $aps to data in the database! but usesever# da# ter$s that describe user business environ$ent

What is the role of an Universe in Reporting:

-he role of an universe is to provide an eas# to use and understand interface for nontechnical Web Intelligence users to run .ueries against a database to create reports andperfor$ data anal#sis

Best Practices to adopt while designing SAP BO universe,

Being the cornerstone of the Business Objects se$antic la#er! universe designbeco$es one of the $ost i$portant aspects of getting the right data out there in ti$e foranal#sis and decision $aking

/ollowing are the best practices for to be considered while designing universe!

Anal#sis of end user re.uire$ents is the $ost i$portant task in the process It isstrongl# advisable to spend $ost of the universe develop$ent ti$e and put $uch

effort in Anal#0ing and Planning phases of business re.uire$ents Avoid using auto$atic universe creation wi0ard Universe created using wi0ardwill be co$ple1 and difficult to understand

Insert tables into universe one at a ti$e Use short cut joins whenever possible to reduce no of tables used in a 2uer# 3lass and Object na$ing convention should be in business ter$s! so that it

$akes sense to business users All Objects should have help te1t or usage infor$ation Object for$atting should preferabl# done at the Universe level Pre&build condition objects in the universe rather than forcing users to build

conditions for reports

Use aggregation in all $easure objects & to push aggregation to database whereperfor$ance bottleneck is likel# to affect BO server and database perfor$ance isopti$al 4enerall# aggregation at database level is $uch $ore powerful! and itreduces the volu$e of data to be transported over network

Use custo$ "O5s or 3ascading pro$pts to displa# "O5s where hierarchies andnu$erous values are involved

Use derived tables to define $easure objects dependent on $ultiple fact tables

How to create universe in client system:

In order to build a universe! developer should create a new universe file 3onnectionpara$eter $ust be defined while creating universe file! to allow universe to accessdatabase $iddleware 3onnection para$eter includes definition of a universe which isco$prised of universe na$e! description! 6DB7S connection

Universe Para$eters dialog appears

once connection is established! test the connection to $ake sure its working

Schema: A sche$a is a graphical representation of database structures In Designer#ou create sche$a which #our universe represents

Sche$a contains tables and joins -ables contains colu$ns that #ou eventuall# $ap toobject that business user use to create reports 9ou design the sche$a in structurepane b# selecting tables fro$ target database using table browser fro$ Insert $enu indesigner

A good schema design is essential for a good universe.

-here are two t#pes of sche$a!

* Star Sche$a: Snowflake Sche$a

Star Schema , Star sche$a is a relational database sche$a for representing

$ultidi$ensional data Star sche$a consists of one or $ore fact tables referencing an#nu$ber of di$ensional tables

Advantages of Star Schema:

Provides highl# opti$i0ed perfor$ance for t#pical data warehouse .ueries 6educes the nu$ber of joins between the tables and hence faster perfor$ance

Disadvantages of Star Schema:

6e.uires $ore a$ount of storage space

Star Sche$a is used for both si$ple data $arts and ver# large data warehouses

Snowflake Schema: Snowflake sche$a is a $ore co$ple1 data warehouse $odelthan a star sche$a! and is a t#pe of star sche$a It is called snowflake sche$a!because data $odel rese$bles snowflake

Snowflake sche$a helps in $ore nor$ali0ation and eli$inates data redundanc# -his isbecause! a di$ension data is grouped in to $ore tables instead of one large table

Advantages:

8o redundant data! hence easier to $aintain When we nor$ali0e the di$ension! di$ension will not be parsed

Disadvantages:

In snowflake $odel! .uer# process takes longti$e as $ore tables are joined Increases nu$ber of tables end users should work with

Snowflake data $odel is good when data warehouse is s$all for large data warehouseenviron$ents star sche$a is idea to i$ple$ent

Step !. Adding "a#les to universe: A table browser co$ponent available in universedesigner allows developer to select tables fro$ database and place the$ in structurepane! which shows a visual representation of a ph#sical database structure or sche$a-able browser is a independent co$ponent which can be invoked fro$ toolbar button orb# right click on structure pane

Step $. %reating &oins ' %ardinalities: Once $ore than one table is inserted intosche$a! we need to create joins between tables! as the# allow data to be retrieved in a$eaningful wa#

What is a &oin( A join is a condition that links the data in separate but related tables -he tables usuall#have a parent&child relationship If a .uer# does not contain a join database returnsresult set with all possible co$binations of rows in a table! such a result set is called3artesian Product

A join between two tables deter$ines how data is returned when both tables areincluded in a .uer#

%lasses:

3lass is a logical grouping of objects and conditions with in a universe! based onbusiness criteria 3lasses are represented as a folder in universe 3lasses are createdin universe pane 3lasses can also contain sub class

how to create class,

/ro$ $enu bar click on insert class icon or right click on universe pane and selectclass! class is created in universe pane

+dit properties of 3lass dialog bo1 appears where #ou can na$e class

Detail! 7easure objectsObjects are grouped into classes Using objects! end users can built .ueries to generate

reports

Cow to create objects in class,

/ro$ $enu bar click on insert object icon or right click on universe pane and selectobject! object is created in universe pane under selected class! below is the objectdefinition

other than above $entioned functions in object! BO universe supports one $orefunction which is aggregate aware

What is aggregate aware( Aggregate Aware is a feature that $akes use of predefined aggregate tables to

enhance the perfor$ance of S2" transactions It is used to i$prove the speed b# whichaggregates are calculated in the database -o set up aggregate awareness in auniverse! #ou define one or $ore objects using the EAggregate Aware function -hes#nta1 for this function is as follows,

EAggregate Aware>aggregate table * aggregate table n?

-he argu$ents of this function are all the na$es of alternative aggregatetables When #ou for$ulate the s#nta1! #ou should be aware of the orderof the argu$ents -he precedence is fro$ left to right% this $eans thatSAP Business Objects deter$ines the aggregate to use beginning fro$ theleft$ost argu$ent

As a general rule! #ou should enter the $ost aggregate table as the first argu$ent! the ne1t $ostaggregate table as the second argu$ent! and so on 9ou $ust then use the Aggregate 8avigation editorto set up a list of inco$patible objects and@or inco$patible conditions for each aggregate table in #ouruniverse -hese are the co$ponents that cannot be used with an aggregate table 9ou can either set upthese lists $anuall#! or cause the list of objects to be detected b# Designer

Step -. Defining %ondition )#*ects:

A condition object is a predefined where clause that can be inserted in to the selectstate$ent inferred b# objects in .uer# pane3ondition objects are stored in the 3ondition view of the universe pane

3ondition objects of Beach universe and where clause condition is shown below

Advantages of using condition o#*ects in ) Universe:

Useful for co$ple1 or fre.uentl# used conditions 4ives users choice of appl#ing the conditions 8o need to have $ultiple objects

Disadvantages of using condition o#*ects in ) Universe:

Onl# disadvantage of using condition objects! is #ou force the condition onbusiness user to restrict their access to part of the dataset

"astl# we co$plete the universe b# running Integrit# check

%hecking Universe /ntegrity:

As #ou design universe! #ou should test universe integrit# periodicall# Integrit# checkcan be perfor$ed in two wa#s
