Cognos 10 Framework Manager: Overview

Examine Framework Manager

The next step is to validate the model to ensure the reports build on top of the model are

correct. Well follow simple steps to examine the Framework Manager.

Framework Manager: View

Framework Manager contains the three views:

Physical View

Business View

Presentation View

Physical View-

In this view information on physical data sources is stored. Represents the physica

structure of the data sources. It contains the Query Subject (i.e; tables) imported from the

Data Base with appropriate joins between them where the actual data used primarily for

informational purposes resides.

The data sources can be of the same or different varieties. When you import metadata,many of the properties of the data sources are configured automatically based on the



4/21

information gathered during the import process. After import you can also define otherattributes of the physical data source, such as join relationships, that might not exist in thedata source metadata.

Create Alias Table

Alias Table-

Alias Table is actually same as physical table in Framework Manager but with the

type of Alias.

Alias Tables play a important role in designing a physical view.

Alias table is Shortcut to a Query subject in Framework Manager.

Alias Table also contain all the Query Item , which the physical table contain.

Purpose to create Alias Table-

It simplifies the schema structure and using alias table we can create a

star/snowflake schema in business view.

Alias Tables are created to simplify the data model by giving a specific name to a

them, which is easily understandable by end user.

Steps to create an Alias Table-

To create Alias Table Right-click on a physical tableCreate Alias Shortcut.



5/21

The alias table (i. e; Shortcut to Dim_Segment) appear in the physical View.

Specify a name to alias table.

Similarly you can create more alias table according to reporting requirement.



6/21

To view all objects of the physical view expand the imported database (i.e; project), which contain

Physical Data model, Query Subject (i.e; Physical Tables), Query Item (i.e; Physical Columns), and

Key Columns etc.

The following objects define below-



7/21

Physical Data Model-

Physical data model contains the Query subject (i.e; tables) and Query items (i.e;columns) are contained within a query subject imported from the Datasource.

Physical data model represents how the model will be built in the database. A physical database model shows all table structures, including column name, column

data type, column constraints, primary key, foreign key, and relationships between

tables.

Physical dimension table-

It contains the key column and physical attribute.

A physical dimension table is a broad grouping of data such as products, dates and

markets.

Key Column-

Key Column uniquely identify each row in a table.

Physical Attribute-

Physical Attribute represents a single characteristic such as product name, and

region name, customer name etc.

Physical Fact Table-

It contains the foreign keys associated with its physical dimension table.

It contain the measure column which is used for evaluate value.

Measure Column

Measure/Facts are the key performance indicator that you want to evaluate.

A Measure is a number or quantity that records a directly observable value o

performance.

Measures include facts or variables typically stored as numerical fields, which

provide the focal point of investigation.

Business View-

8/21

Business View Represents the logical structure of the information in the Framework

Manager. The physical schemas are simplified and restructured in this view and all the

Business logics are implemented. It specifies the mapping between the business models

and the Physical view schema. The Business Model can contain one or more business

model objects. A business model object contains the business model definitions and the

mappings from logical to physical tables for the business model.

What is Business View-

It contains the business view of the metadata such as business calculations, filters

and so on.

It contain organized model by creating separate views for each user group that

reflect the business concepts familiar to your users.

Create Business View-

Create one or more optional namespaces or folders for resolving complexities that

affect querying using query subjects or dimensional objects.

Create one or more namespaces or folders for the business view of the metadata tha

contains shortcuts to dimensions or query subjects.

Steps to create a Logical Table in Business View-

Go to Physical ViewRight click CreateNamespace



9/21

Specify a name to a New Namespace.

To create a Logical Table in business view , you should follow-

Right click on Business View CreateQuert subject



10/21

New Query Subject window will appear. Specify a Name and Type that you want to

define to this New Query subject .By default it will provide you a data type, please try to

keep it same.

After Specify Name and Type to this New Query subject, click Ok.



11/21

Query Subject Definition window will appear. Drag and drop the objects from

Available model Objects to Query Items and Calculations.

After drag and drop the objects, Click ok.



12/21

Similarly you can create more Logical Table in Business view. We can view the

Logical table in business view, which we have created.

To view all objects of the business view expand the Business Data Model, which contain Query

Subject (i.e; Logical Tables), Query Item (i.e; Logical Columns), and Key Columns etc.



13/21

The following business view objects define below-

Business/Logical Data Model-

Business /Logical data models represent the abstract structure of some domain o

information.

A business/logical data model describes the data in as much detail.

Business/Logical model built to represent the business view of data, which is

easily understandable to end user.

Business/Logical Dimension Table-

It contains the key column and logical attribute.

A business/logical dimension table is a broad grouping of data about a major

aspect of a business, such as products, dates and markets.

Key Column-

Key Column uniquely identifies each rowin a table.

Business/ Logical Attribute-

Business/Logical Attribute represents a single characteristic such as produc

name, and region name, customer name etc.

14/21

Business/ Logical Fact Table-

It contains the foreign keys associated with its business/logical dimension table.


Measure Column

Measure/Facts are the key performance indicator that you want to evaluate.

A Measure is a number or quantity that records a directly observable value o

performance.

Measures include facts or variables typically stored as numerical fields, which

provide the focal point of investigation.

Purpose to Create a Business/Logical Model-

We can create one or more optional namespaces or folders for resolving

complexities that affect querying using query subjects or dimensional objects.

Business/Logical model built to represent the business view of data, which is easily

understandable to end user.

Create one or more namespaces or folders for the business view of the metadata tha

contains shortcuts to dimensions or query subjects.

The above screen shows the Business/Logical Model, which contains Dimension and Fact table

and relationship between them. In the above screen the blue rectangular box shows the

dimension table and red rectangular box shows the fact table. The Schema

Dimension table-

It contains the key column and logical attribute.

A business/logical dimension table is a broad grouping of data about a major aspect

of a business, such as products, dates and markets.

Business/ Logical Fact Table-

It contains the foreign keys associated with its business/logical dimension table.


Description about Logical Dimension Table and Logical Fact Table-

Logical Dimension Table-

D0 Time ( Time Dimension Table )- It contain the key column, and all theinformation about Time Dimension ( i.e; yearly, half yearly, quarterly, monthly, weekly,day). This dimension table is used to evaluate Measure value across the time. D1 customer (Customer Dimension Table) -It contain the customer key column,and all the information about Customer Dimension ( i.e; customer name, customer type,customer segment description etc). This dimension table is used to view the customerinformation and evaluate Measure value across customer detail.

D2 Market (Market Dimension Table) -It contain the market key column, and allthe information about Market Dimension ( i.e; market description, region, district, areaetc). This dimension table is used to view the market information and evaluate Measurevalue across market detail. D3 Order( Order Dimension Table)- It contain the order key column, and all theinformation about Order Dimension ( i.e; order status, status date, previous status etc).This dimension table is used to view the order information and evaluate Measure valueacross order detail. D4 Product (Profit Dimension Table)- It contain the profit key column, and allthe information about Product Dimension ( i.e; Product description, color, size, type

16/21

F0 Rev Base Measure (Fact Table)- It contain the foreign key column, which isassociated with all the dimension table. It contain all the fact/measure value, which is anumeric value. This table is basically used for the profitability measurement.

Presentation View-

Represents the presentation structure of the Framework Manager. As the names specifies this

layer is used for Presentation of required tables and columns to the users. Provides customized

views of Business model to users, exposes meaningful data to the user and organizes data the

way users analyze. The columns pulled in this layer are directly visible to the users.

The Presentation layer provides a means to further simplify or customize the business modelfor end users. Simplifying the view of the data for users makes it easier for users to craftqueries based on their business needs. For example, you can organize columns differently thanthe table structure in the Business Model and Mapping layer, show fewer columns, andrename columns so that they are more understandable to users.

Create a Presentation view-

Go to Business viewRight clickCreateNamespace

Specify a name to a New Namespace.

To create a Presentation Table in presentation view ,you should follow-

Right click on Presentation View CreateQuert subject



17/21

New Query Subject window will appear. Specify a Name and Type that you want to

define to this New Query subject .By default it will provide you a data type, please try tokeep it same.

After Specify Name and Type to this New Query subject, click Ok.



18/21

Query Subject Definition window will appear. Drag and drop the objects from

Available model Objects to Query Items and Calculations.

After drag and drop the objects, Click ok.



19/21

Similarly you can create more Presentable Table in Business view. We can view the

Logical table in business view, which we have created.

Creating Data Model Dimension and Fact Joining

For creating relationship between different dimension tables and fact table, go to Diagram

tab as shown in above screen and select relationship icon from the tool bar menu. Then

select the query item from table and drag it to the fact table query item with same name

(Remember that ,Relationship Icon- )



20/21

The following screen shows you relationship (one-to-many) between dimension table and

fact table, and join operator. press OK.

The following screen shows the Data Model, which shows the relationship between

dimension table and fact table. This schema is known as Star Schema.
