I will try to continue with this exercise, even though I don't claim that it is easier to express in relational algebra (unless it is out of RDM's scope).

output = f(A,B,C);

I am assuming you want me to provide the function f as a relational expression. I am assuming you will allow me inputs A, B, C (which are not sufficent). What do you want the ouput to be? Received on Sat Feb 28 2004 - 03:54:58 CET
