I read an on-line article by Pinal Dave (he writes a blog on SQL Server) where he makes many suggestions as to the naming conventions but never mentions the unique index key. So that brought up the question.

He wrote several. I have 4 out of 5 books series SQL Programming Jos Pros 2. He had a 35 days SQL quiz and randomly selected 1 person from USA and one from all other world as a winner.
