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,
