Nice approach, Orlando. The term "as a data source" is pretty succinct.

Dr. Who, my guess is that if you put SQL Server on your resume, the reader of the resume will understand that you know how relational databases work in general. Granted, this does assume some level of technical competency of the reader, which may or may not be a safe assumption. If the reader is the HR person filtering the stack of resume, you'd be out of luck. It's probably best to take Orlando's approach.
