For me personally, I think the above would work great.

But now I am trying to make the db understand on its own, so the above looks like the below to it:

T1 (id1, f1)
T2 (id2, f1, id1)
T3 (id2, f2)

Here the db can say type T1 things have attribute f1. And type T2/T3 things have attributes f1, f2 with multiple values and to f3(id1). It doesn't know enough. Am I expecting too much? Received on Sat Jan 13 2007 - 00:38:02 CET
