My title is "SQL Server Database Administrator/Data Warehouse Specialist".

I like it and it describes very accurately what I do. This doesn't fit too well on business cards but I don't require them for work so that's not an issue there. Sadly, this precludes me from putting business cards into fishbowls at restaurants to win free lunches. So the next time my girlfriend is ordering some for work, I'll get her to make some for me with title "Lunch Draw Winner".
