An association class is derived due to many-to-many relationships between two classes.
Is it true?

Association class can be derived from two situations:
first,many to many relations
second,one or more attributes of the class can have multiple values.

An Association Class is used to show properties of an association itself. Of course it can be used on many-to-many relationships, as it can be used on any other.
