An association relationship is very similar to an N:M or many-to-many relationship except that the intersection table has attributes of its own.
An association relationship are often delineated as matched, one-to-many, or many-to-many. Basically, associate association relationship between 2 or additional objects denotes a path of communication between them in order that one object will send a message to another.
