I basically haven't got a choice, although I am being named "the database expert" I do what I am being asked to do. Some of us haven't got the luxury of being a specialist, although I spend a lot of my idle time reading and learning to be a better man in the job. I find myself often arguing my cases with people who are just doing sloppy jobs. Trying to be a specialist does not however stop me from learning everything I need to know to implement solutions that require various skills and knowledge of a whole system, not just a narrow part of the subject.
