Applying your logic, that set elements are only determined by mere insertion, then in your db the following sets would be acceptable?

Color = {red, green, banana, 8}
Fruit = {apple, grape, brown, 7}
Number = {5, 6, blue, peach}

While there are sets where the relationship between it and its elements is very, very general, a system built with only weak/general relationships, would not be useful for many applications. Received on Sat Feb 28 2004 - 01:58:33 CET
