Entity-Relationship Diagram Selector

E-R Diagrams enables you to create an Entity-Relationship Diagram or work on an existing one.

An Entity-Relationship Diagram is made up of Entities, Weak Entities, Relationships, IS_A Relationships and Connections. The diagram editor is used interactively to draw and modify Entity-Relationship Diagrams.

You can select an object by typing its name in the Enter name field. If the object does not already exist you are asked if you want to create it. Wild cards are allowed in this field. Alternatively, click on List All and then scroll through the list until you find the object you want. Click on the name to select it.

A selected object is shown in reverse video (highlighted). You may highlight more than one object if required. Pop up the selector menu and choose an operation. Some commands are not available if you have highlighted more than one object.
