I share this sentiment. The apps will come and go, the real value is in the data. If the database can cover its ass, I am less concerned about ham-fisted developers randomly messing it up with ill-conceived DML. It's not that they are malicious...it just happens. I have seen devs that code in Erlang, Haskell and even Assembly...run in terror at doing some SQL. It's weird. Trust but verify. And hire persnickity, passionate DBAs.
