Purpose:Two objects can be considered to be related by aggregation if there is a strict 1:1 relationship between the objects. This means that if the source (parent) object exists, then the target (child or owned) object must exist. In TopLink, it also means the data for the owned object is in the same table as the parent. @author Sati @since TOPLink/Java 1.0
