Enhanced Entity-Relationship (EER) diagrams are created by
Add Diagram in the Model Editor.
You may create any number of EER diagrams just as you may create any
number of physical schemas (databases). Each EER diagram opens in a
tab below the toolbar. A specific EER diagram is selected by
clicking its tab.
Clicking an EER diagram tab navigates to the canvas used for
graphically manipulating database objects. The
Toolbar is on the left side of the canvas.
This tool is for creating and editing EER diagrams for a model. To edit an existing database, either reverse engineer the database to create a model, or synchronize your model to a database. For additional information, see Section 220.127.116.11, “Reverse Engineering a Live Database” and Section 9.5, “Schema Synchronization and Comparison”.
