David, you've hit the nail on the head. Dan

I'm an old Microsoft Access user, so I just need to double-check on this with MySQL: I want to relate two tables (let's call them "users" and "priveleges") in a many:many way. That is, each user may have multiple priveleges, and each privelege may have multiple users with that privelege. Here are my questions: a)I'm assuming that under MySQL I have to create a third table that maps between them? (Let's call it "users2priveleges".) b)I'm assuming that there is nothing special I need to do to get, for example, all the priveleges with a user (just the standard join stuff with x=y and y=z or something like that)? c)I'm assuming that from an optimization point of view, there is nothing I can/should do beyond optimizing the links, i.e. making sure the related fields are indexed? Thanks.
