RE: FK Constraints

A disaster waiting to happen; it's not if one will happen, it's when. Applications, no matter how well written, will, sooner or later, lose transactional control because of design flaws, new front ends that don't enforce ACID transactions (or interfaces from other systems) or other acts of development or network failure. DON'T DO IT! I've seen too many projects fail, and spent too many hours trying the impossible: cleaning up integrity violations after the fact. If you want real life examples, I'll be happy to supply off-line (protecting the not-so-innocent)
