Hi all,

I'd like to set up a discussion (if necessary) about two different ways to implement N-to-N relationships: using a N-to-N intermediary table or, suppose an A and B tables situation, creating the primary key of the table B with the plus a sequencer.

I'm thinking on going the second way, but decided to ask the list if anybody sees any potencial problem in it, like for performance or anything.
