>>Last time I had contact with these folks in person, they were doing both jobs. And since I'm doing part of both, the distinction hasn't affected me. I guess in places where they'd hire those, they'd probably have the responsibilities split.

Craig, that kind of breakout is the exception rather than the rule. The Data Warehouse and BI area could be separate types, or you could have 1 or more individuals doing both. DBA might write procs as well.

Not challenging what you're saying in your own environment, but more often than not, what you're describing are roles, versus types of people. I've played roles 2 through 5 for a single client/employer (sometimes out of necessity).
