>So, the question i(d)s: business keys, use them or not, hide them or not. Ladies and gentlemen, I'm waiting for a wise word on the subject.

I would say, the BEST method is...

Use them, don't use them, hide them, make them visible...

Depending on your users wants, and needs, and a bit of what they are used to.

Well, that clears that up!
