Add associations to an entity

When you define an association, you can add it under either of the two entities in the relationship. You add an association to an entity just as you add an attribute. You must right-click the entity and select Add Association.

The Association dialog box opens in which you set the association’s properties. In most cases, you only need to look at these properties:

• Source Entity Name—By default, the entity to which you are adding the association is selected as the source entity. You should retain this default setting.
• Source—Select One or Many depending on the role you want the source entity to play in the relationship.
• Target Entity Name—Select the target entity from the drop-down list.
• Target—Select One or Many depending on the role you want the target entity to play in the relationship.

When you complete setting the properties, click OK.

The association is displayed in the Vocabulary tree under both entities with the relevant association icon.
