You create data models by choosing database tables from the Table Catalog and assembling them as topics in the Content frame. The Table catalog is a listing of the tables available in the database. Once connected to a database, you can display the Table catalog and drag the topics that you want to include in the data model to the Content frame.
To add a topic to a data model:
In the Query section, select DataModel, then Table Catalog, or press F9.
If you are not connected to the database, you are prompted to log on. Once connected, the Table catalog is displayed listing the available database tables.
Drag tables from the Table catalog to the Content frame.
Each database table you place in the Content frame is converted to a topic in a data model.
