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... Received on Fri Aug 09 2002 - 16:59:28 CDT
