I'd say it takes you from beginner to a fairly advanced level where you can really dig into related topics. We don't have a certification target for this one.
I'd lean toward developers, who maybe have lots of different technologies and are comfortable with programming, but haven't gotten around to SQL yet. If someone is a DB admin, he *should* know what's in here very well, but if not, it's for him.
