EER diagrams are created by double-clicking the Add Diagram icon. You may create any number of EER diagrams just as you may create any number of physical schemata. 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. On the left side of this page is the Vertical Toolbar.
