Indeed. :-)

I could answer:
"Moving object business logic from objects to the database usually ends up in a disaster."
(please ignore)

A more useful answer:
Maybe we are still missing the right approach in our object-oriented programming languages, as we know them today. Indeed it is very difficult to come up with a design, that lasts to be reused with multiple different applications.

Maybe inheritance is the wrong approach and we need a more loosely coupled system of dynamic delegates. (Tables and relations? :-) )

Kind regards,
Carl
