Like everyone else, when I am asked the question about my job title from someone outside "the know" I usually respond with "IT". I'm a "Consultant" with my company and labeled a "Database Administrator" while on the job (don't ask). My resume goes with the Database Administrator title.

When asked the same question from people in "the know" I like to be a little more creative and go with "Master Databaser" or "Senior Databasing Executive".

Here's a discussion we had on how to describe what we do to other non-IT folk, the next step in labeling your professional self.
