Agreed. But that's one of the reasons I dislike relational, actually :-) It seeks to divorce the logical from the physical.

With Pick, I let the real world dictate the physical data structure. I then impose relational theory over it. The relational model as implemented divorces the real world from the physical data structure by imposing set theory as a wall between the two :-( That is a MAJOR failing imho!

good idea to burden them with too much input. Hex always thought of his reports
