I have recently been testing a product called
Versata (mentioned by Date in "What Not How"),
and I was frankly pretty impressed.
The idea is to take the application logic
out of programs and express them as rules
(business rules is the term). So the same
thing that has been done to data (taken out of
programs and files and put into databases)
is being done to logic.
In Versata it is of course a layer on top
of the database server, but using the product
the difference is pretty transparent.

A more "pure" approach is the one taken by
Alpora Dataphor (www.alphora.com), but I have
not had the time to test it yet.
And the solution, in my mind is so _obvious_
that I just can't understand how people don't
get it. It probably has to do with the different
culture of 'database guys' and 'programming guys'.
But I remain optimistic...
