Re: Database Foreign key constraints vs Application Maintained Constraints

  Since data integrity violations should not occur, I guess that one can as safely assume that their should never be any bug in the middle tier java API, that nobody will ever mistype anything, and that all distributed transactions will always safely complete and that nothing will ever keep hanging in limbo.

   Brave new world ...

If I were you I wouldn't let your developers refactor their schema, with or without FKs. Don't know why, not feeling fully confident.
