That's exactly my point. your comment: "Any time you want to start putting application constraints into a database, you should stop thinking and just do the simplest thing possible. That will, most likely, not involve a database." is too general, because it doesn't take into account the fact that in many, MANY, cases the constraints are data (to someone).
