5.2 Representing model elements
UML 2 starts with three concepts, object, action, and association.
Object: An object is used to represent some thing.
Action: An action is used to represent something that happens.
Association: An association
is used to represent some structure.
It represents a structure that is present in the system or its environment
and not only in the model.
