>PMFJI, I am also working on a framework and can't seem to decide what to put into the BO class. Can you (if you don't mind) share some brief ideas of what to put into BO class?

My "base" BO class most has methods that just pass calls down to the DE class. It's when I create specific BO subclasses that I put anything else in. The BO classes are where I have validation, for example.
