public class AggregateCollectionMapping
Purpose: The aggregate collection mapping is used to represent the aggregate relationship between a single source object and a collection of target objects. The target objects cannot exist without the existence of the source object (privately owned) Unlike the normal aggregate mapping, there is a target table being mapped from the target objects. Unlike normal 1:m mapping, there is no 1:1 back reference mapping, as foreign key constraints have been resolved by the aggregation.
