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. 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.
