Yea, Charlie, I have thought about this since I posted the question last night, and I think your synopsis is really what I was taught, and I mish-mashed it into my own meaning.

Glad I was set straight. :) Charlie Griefer wrote: > i was taught that if you find yourself with a many-to-many > relationship, just make sure you go back and re-examine whether or not > it's truly necessary. > > but if it is necessary (and certainly, many times it is), then you > would do your junction|cross-ref|intersection|whatever table to > facilitate that relationship. > > On 12/7/05, Russ <[EMAIL PROTECTED]> wrote: > >>I took a course or two on database design and I don't remember anyone >>teaching us to avoid cross ref tables.
