One advantage of working in an over administered environment is it is almost impossible to incorrectly update live data. Even simple data changes we (as developers, I guess DBAs can do whatever the f*ck they want
but they don't really have an interest in the data, so never want to change it anyway) make have to be scripted and run by a DBA in our pre-production environment. Frustrating at times, but probably a good idea so that you don't forget any 'where userid = 'xxx'' clauses.
