• Cognos Framework Manager is a metadata modeling tool

• Cognos Framework Manager provides the metadata model development environment for Cognos 8.

• A model is a business presentation of the information from one or more data sources

• The model provides a business presentation of the metadata

• The model is packaged and published for report authors and query users

Introduction to Framework Manager


http://maxonlinetraining.com/cognos-online-training/


• Report authors use the published package in Cognos Report Studio to create standardized reports.

• Query users use the package in Query Studio to create adhoc queries.• A project contains a model, namespaces, data sources, Query Subjects, Query

Items and packages• Educating the query engine on how to structure the query• Critical for business success because data accuracy depends on the design• We can create model using Model Design Accelerator




Continued…• After define a Framework Manager Project and namespace, one can publish one

or more packages containing metadata information to the Cognos Connection.• BI users use the model to analyze and report on their data sources.

Project: The Project is the container for all the components used by Cognos Framework Manager models, packages Datasource etc

Model:A model is the set of related query subjects and other objects required for one or more related reporting applications.

Packages: Packages are collections of metadata that we are going to publish in Cognos Connection for use by the business users.

Framework Manager Objects




Data Sources: A project can contain data from one or more data sources

Namespaces: A namespace uniquely identifies query items, query subjects

and other objects. Import different databases into separate namespaces to avoid duplicate names.

Parameter map

Parameter Maps are substitution tables that are populated when the package is published



Query Subjects: query subjects refers tables in database. A project is built upon query subjects.There are 3 types of query subjects:

- Data source: A data source query subject directly references data in data source . A single Framework Manager project can contain data source query subjects from one or more data sources from one or more vendors. This provides heterogeneous database access. Data source query subject can be enhanced by adding filters or calculations to create additional query items

- Model: Model query subjects can contain query items from an arbitrary set of data source query subjects. Model query subjects can be enhanced by adding filters or calculations to create additional query items.

- Stored procedure: The stored procedure query subject operates much like a data source query subject in that it defines a set of query items that are available to the model from the underlying data source. Stored procedure query subjects cannot be enhanced by filters or calculations.

Query Items:

Query items are contained in query subjects. For example, a query subject that

references an entire table contains query items that represent each column in the table.

Note Calculated query items can have a dramatic impact on the performance of your SQL queries. It is strongly recommended that calculated query items use database-only functions or are incorporated directly into the database when possible.

Usage property

When a business user interacts with a model, the behavior of the data will be determined by how the properties of the query item are set. For example, when the business user adds a query item that references a numeric value to a report, will the value be totaled or will it be averaged? Maybe nothing will happen. Cognos Studios determine the proper behavior for the data referenced by a query item by looking at the usage of the query item being referenced

Continued…



• Identifiers If the source column is a database key or date/datetime, the query item usage will be set to an Identifier.• Facts If the source column is a numeric value or a time interval, the query item usage will be set to Measure.• Attributes If the query item is not an Identifier or a Measure, the query item usage will be set to Attribute.

• Regular Aggregate• The Usage property is important because of the impact that the property has on the aggregation setting of a query

item. The Regular Aggregate property, as with all the other properties, is set during the initial metadata load. This property determines how the values of a query item will be calculated when a summarization is applied to those values.

• When a query item is determined to be an Identifier or an Attribute, the Regular Aggregate property will be set to Count. This means that if a business user applies a summary to a column of Identifiers or Attributes, the value displayed in the summary cell will be a count of the rows returned by the report or query. If the query item is an Attribute or an Identifier, and the data type is a Date, the Regular Aggregate defaults to Unsupported. Applying a summarization to a query item with an Unsupported Regular Aggregate property will have no effect on the data.

• When a query item is determined to be a Fact, the Regular Aggregate property will be set to Sum. In this case, applying a summarization to a column of Facts, the value displayed in the summary cell will be the total of all the values added together.

•Physical ViewThe first view in our model is the Physical View. This view is used to hold the query subjects and relationships used to build the

model. The query subjects in this view should be unmodified views of the source tables. This ensures that simple select statements are sent to the database, which prevents additional metadata calls at runtime.

•Business ViewThe second view is the Business View. This view contains query subjects that have been optimized for use by the business user.

This is where items are renamed, folders are created for organizational purposes, query subjects are consolidated, and, when necessary, query subjects are merged.

•Presentation ViewThe final view is the Presentation View. As the name implies, this is the view of the model that will be presented to the

business user. The query subjects in this view are organized to make sense for the business user. Usually Business View query subject short cuts

•Star Schema and Snowflake A star schema is a database design optimized for reporting. The design is based on a central fact table that is surrounded by dimension tablesSnowflake-- it contains a dimensional query subject that is not directly joined to the central fact table

•Fact TableIn its simplest terms, a fact table contains measures that will be aggregated in a report or some other tool.

A fact table is used to hold transactional data and the keys to the attributes that describe those transactions

•Dimension TableA dimension table, again in simplest terms, is a table that does not contain any measures. In a database, a

dimension table hods attributes, or descriptive values, that can be applied to one or more fact tables. nonconformed, conformed, and role-playing. When a dimension can be used by more than one fact table with consistent and give correct results, it is known as a conformed dimension.When a single table is used to provide different dimensional information based on a join or filter, that table is said be a “role playing” or “alias” table. A common example of this is an employee dimension.

A Framework Manager project appears as a folder that contains a project file (.cpf) and the specific .xml

files that define the project. The files in a project folder are unique to each project

The contents of a project folder are..

<project name>.cpf : The Framework Manager project file, which references the .xsd and .xml files used to

define a project

model.xml: The actual model data created by Framework Manager users

Preferences.xml: The preferences for Framework Manager projects

customdata.xml: This file contains the layout information for the diagram. If this file is deleted, layout

information is lost. An automatic layout will be applied.

repository.xml: The logged version history for each project or segment that was added to a repository.

This file exists only if you have added projects to a repository

Project File

After create or open a project, the project page appears. This page contains several panes and views that one can use to view and modify the objects in a project

Project Viewer:The Project Viewer shows the objects in a project in a hierarchical view. You can use the Project Viewer to view, modify, and create these objects:Query subjectsData sources Namespaces Parameter mapsFoldersLinks CalculationsFiltersPackages

The Project Page


Object Viewer:

The Object Diagram View shows the relationships between objects in a project in a diagram. Relationships between query subjects are shown as lines with cardinality notation.

The Object Explorer Views shows Query Subjects and relationships between Query objects in the form of Icons

Dimension map is used to create Regular dimension.


Properties pane:

The Properties pane shows the properties of the objects you last selected in either the Object Explorer View, Object Diagram View, or Project Viewer. Object properties are set during import, and some property values can be modified during modeling. One can use the Properties pane to add, modify, or delete the properties of objects

Tools pane:

Tools pan will shows Design language ,Active language ,Tasks and all the statistics in detail
