Adding or deleting objects from a physical data model diagram
You can use the diagram palette, the Properties view, and context
menus to add or delete objects from a physical data model diagram. You can
also copy and paste an existing data object to create a new data object with
the same properties.
Adding related objects to a data diagram
You can add related objects to data model diagrams. This action automatically determines which objects have relationships to existing data objects and then adds them to the diagram.
Adding a diagram shortcut to a data diagram
You can create a shortcut to another diagram into a data diagram to allow navigation between related data diagrams. You can use diagram shortcuts to group diagrams together by subject area.
