I agree. Some app logic is best performed in the backend. Especially if the
logic is storage intensitive or deals with advanced storage
constraints/rules. That's one of the reasons I wrote Pl/Java. In essence, I
don't think we disagree on anything. The only thing I'm reacting to is the
term "app-server" which I think is badly chosen. Stored procedures and
functions doesn't make a database an app-server, no matter what you put in
them.

You can write your own functions in C and thereby get all the process
control you want. Or if you want to make life easier and get a more portable
solution (by my standards that is) why not use Java?
