EER diagrams are created by double-clicking the
Diagram icon. You may create any number of EER diagrams
just as you may create any number of physical schemata (databases).
Each EER diagram shows as 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 this page.
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 184.108.40.206, “Reverse Engineering a Live Database” and Section 9.5, “Schema Synchronization and Comparison”.
