Cherie,

Can you tell me which normal form a many-many relationship violate? Thanks.

I know how to implement it. But I'm curious about its violation of normal form.

A many-to-many relationship violates the rules of normal form. You have to put the extra table in between to have one-to-many on each side of the intermediate table. Thus you eliminate the many-to-many relationship.
