FM Model



Framework Manager:

•        FM is a windows based metadata modeling tool to build models for designing reports

•        It is used to create projects

•        Use FM to access the metadata from one or more data sources

•        The data source may be homogenous ore heterogeneous

•        When we are working in FM we work with the projects

 

 

•        Project includes model, namespace, query subject, query item, folders, shortcuts, parameter map, packages, data source, filters and calculations

•        Project is a store in file system with extension .cpf ( Cognos Project File )

•        A project is a set of files that describes the metadata in one or more models

•        A project also known as presentation layer/metadata layer which is derived from the physical layer database

 

 

•       A project created using FM appears as a folder and contains the following set of files

     * Project.cpf ( Cognos Project File)

     * Model.xml

     *Prefer.xml

     *Customdata.xml

•       The files in the folder are unique to the project

 

 

MODEL:

•        Model is business representation of information from one or more data sources

•        Model is a set of related query subjects and query items defined in a project, required in one or more reporting applications

•        A model is an end user interface which provides an access to data from the database

•        A model provides a gateway between user and database

 

 

•         A model is created to fulfill user/report requirements defined in business vocabulary

•         A cognos Architect/Modeler is responsible for creating models by fulfilling business requirements

Report Development:

•         An Application Developer designs reports by fulfilling report requirement specifications using models

•         Carry the following tests to test each report application in a test environment

     * Unit testing             *System/Data validation testing

     *Performance testing       *User acceptance testing(UAT)
