These two are the same thing essentially: there are major differences between the software model and the database model for RDBMSs, for non-trivial applications. I.e. there are two different maintenance entities, both requiring work and constant synchronisation. It has certainly been proven to me that (some) ODBs remove this problem almost completely.

My experience is that the "further elaboration" (i.e. different elaboration) is a mild form of masochism more than anything else! (a form of masochism many of us are forced into in many situations of course).
