Object - Class Diagram (UML)

About

A class diagram is a diagram specified in the UML standard by showing:

the classes (the class is the entity) with its attributes and methods.
and the relationships between them

By comparison with a classic entity relationship model, it adds the behaviors (ie method) of each entity to the model.
