 simple rule:

 we have object A and object Z.

 if we have a pointer from object A to object Z then its aggregation.(no pointing from Z to A ,since it maks a simple relation).

 if object Z cannot exists in the system without object A, then its composition.

 its not that hard, even more ITS NOT THAT USEFUL. why? beacuse no body uses this stuff to the fine lines, its a loose model that lets you grasp what you want from the system.
