A connection definition that tells the model how to connect to the source database The data source definition allows Framework Manager to connect to the database and query it for the available metadata that is, the tables and columns that can be accessed from the database When a report is written against the model, the data source definition tells Cognos 8 where to connect to query for the data that will go into the report The data source definition in Framework Manager actually references a data source definition in Cognos Connection This fact allows you to re-point a Framework Manager data source to an alternative Cognos Connection data source to access a different instance of a database of the same design for instance from a development version to a production version of the database with the Framework Manager macro facility to substitute values in the model at runtime of a report to get the desired results This facility can be used for implementing row-level security or dynamic database selection, for example A parameter map can be populated manually or via a query This will be covered in the Macros section in 16 .
