> Does the above model work?
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 Fri Jan 12 2007 - 17:38:02 CST
