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.

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.
