Hi list,
Me again ...

I've got to compose some objects by inheritance of parent classes (Is A), I'm now on the point of building the actual object tree and I was wondering what is the preferred mechanism for aggregation (Has A) and controlling children types ... can I do this in the schema ?

Thanks,
LP.
