Re: A (False?) Reason that Many-to-Many Must Have at Least One Descriptive Attribute

Mmm... I don't think so because, although many-to-many relationship is not an entity, it is still a relational schema in the relational DBMS. And, from a relational schema a set of FDs exists although the FDs are trivial.

I have not found other DBMS books that says something about membership algorithm.
So, I think the algorithm in the book has some missing prerequisites.

Regards,
Eus
