Composite Association |
Select this option to create a composition or deselect it to create an association that isn't a composition. A composition is an association in which the source object "owns" the destination object. You might think of the source object as a container for the destination objects. For inserts, updates, and deletes, the destination entity object is considered part of the parent entity object. |
