aggregation/ composition/association

Posted by florian troesch on August 24, 2001 at 11:47 AM

Is it right that the difference between aggregation & association
is that in case of aggregation A->B, B can only exist if A does.
Is it futhermore right that the difference between aggregation
and composition is that a composition A->B, can have on the A
side only cardinality 0..1.
