Creating a Data Diagram
A data diagram is a graphical representation of a model or of part of a model.
When you create a data model from a database, the corresponding data diagram is also created.
You can then connect new data diagrams to the data model.
To create a data diagram:
1. Right-click the data model.
2. Select New > Diagram.
3. In the dialog box that opens, select Data Diagram.
4. Click the Create button.
The diagram opens in the edit area.
