The application and the database communicate "only" thru SQL, so there is a lot of metadata that is not communicated between the layers, at least not without a lot of effort. I have to confess that I don't have a lot of experience with 4GL's except for SAS (it had a lousy DB, though).

What I mean is that the app environment is not aware of the structure of the DB without lot's of (hand-) coding.

There has been an artificial layer created between the DB and the UI. You need a lot of code just to get simple stuff the screen. Adding insult to injury you get poor performance.
