Entity-Relationship Model Selector

E-R Model enables you to create the Entity-Relationship Model or work on the existing one. Each project can have only one Entity-Relationship Model. This Entity-Relationship Model together with its Data Dictionary definitions forms the Information Model: the end-product of IM. The name of the Entity- Relationship Model is automatically derived from the project name.

The Entity-Relationship Model is constructed from previously created Entity-Relationship Diagrams. All commands in the Entity-Relationship Diagram editor apart from those that create diagram components are also available in the Entity-Relationship Model editor. The Entity-Relationship Model editor is primarily used as a layout tool.

Creating or editing the Entity-Relationship Model

The Entity-Relationship Model Selector opens containing the Entity-Relationship Model already selected. Select Edit from the popup menu.
