'Has A' vs 'Is A'




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.
