Definition:
A description of a set of objects that share the same attributes, operations, methods, relationships, and semantics [ISO/IEC 19501-1:2001, 2.5.2.9].

Context:
An association is a semantic relationship between two classes. An association is a type of relationship. [Adapted from ISO/IEC 19501-1:2001, 2.5.2.3]

An association class is an association that is also a class. It not only connects a set of classes, but also defines a set of features that belong to the relationship itself.
