Adding Relationships

This feature allows you to manually add relationships to an existing model. This can be useful if you have identified new relationships between existing entities or if you have added new entities to your model that you now need to tie to other entities.

1. With an existing model open, click the Relationships dropdown in the Toolbox.
2. Click the appropriate icon. Choose from the existing types of relationships or choose <New> if the relationship is a type that is new to your model.
3. On the canvas, click and drag from the source entity to the target entity and release the mouse. If you chose an existing type of relationship in Step 2, the relationship is now established. If you chose a new relationship in Step 2, the Add Relationship dialog box appears.
4. Enter a Label for the new relationship.
5. If the two entities have multiple relationships with the same label, you must check Use unique identifier value and enter a value that is specific to this relationship. Two entities cannot have multiple relationships with the same label without a unique identifier.
6. Add Properties to the relationship by completing the Name, Type, and Value fields.
   Note: The Type field will automatically populate when you enter a name, but you can select another type from the dropdown if necessary.
7. Click Add, then OK. The relationship appears.
