Generalization set properties

Use the Properties view to modify generalization sets.
Select a generalization set in the Data Project Explorer view or the diagram editor to modify its properties.

General tab

The following table describes the properties that you can modify for a generalization set:
Property Description
Name Use this field to name the generalization set.
Label Specify a label that is used in diagrams.
Transform As Use this field to specify how the entity is denormalized when you transform the logical data model to a physical data model.
Defining Attribute Use this field to specify the attribute in the supertype entity that is used to characterize the generalizations of the generalization set.
Disjoint Select this option to define a disjoint constraint.

A disjoint is a constraint that is added to a set of generalizations. The constraint specifies that an instance of the supertype can be a member of at most one subtype in a set.

Complete Select this option to specify that the generalization set must be complete.

When a generalization set is complete, an instance of the supertype must be a member of a subtype within the set.

Generalizations tab

Use this tab to change the order of the generalizations in the Data Project Explorer view.
