Hi there,

I've the following modelling situation:

One root class, A, with few attributes.

Eight small subclasses of A, also with few attributes(Tipically, only one).

Our application will perform lots of queries using this class hierarchy.

Quantity of itens registered in the database will grow a lot (millions of registers), without predominance of any of the subclasses.

After explanation, what inheritance mapping strategy do you suggest? Table per subclass or Table per class hierarchy?

Thanks in advance,

Daniel
