ron,

I've usually seen the term "Apps DBA" for the DBA who deals with Oracle Applications.

As for using "development dba" vs "application dba" I was using the terminology of the original poster.

My feeling is, separating these functions just adds to overhead and disconnect in solving problems... more places to point fingers and say "it wasn't me, it was <fill in the name>'s problem"
