Transactions with Compositions
To make an association into a composition, perform the following steps:
1. In the Navigator, right-click an association and select Edit.
2. Select the Relationship panel and expand Behavior.
3. Select Composite Association.
4. If you want to implement cascade delete behavior, select Implement Cascade Delete. If you do not select this check box, Oracle ADF Business Components will throw an exception if you delete a source Entity Object that still has destination as Entity Objects.
