In Enterprise Architect, the default Aggregation relationship is the weak form of the relationship, represented by a hollow diamond. To change the form of an Aggregation link from weak to strong, follow the steps below.
|1.||Right-click on an Aggregation link to display the context menu.|
|2.||Select Set Aggregation to Composite. The diamond is shown as filled.|
Note: If the link is already a Strong (Composition) link, the context menu option changes to Set Aggregation to Shared.
