Summary

The class diagram is used to show how different object interact with each other. The objects has an association with each other as shown in the diagram. The communication diagram describe how the message is passed from an object to an object. The two diagrams have connection in how the object associate with each other. In communication diagram the object that pass message to other object have an association in the class diagram. I have not added additional requirement except from the attributes that were not defined in the transcript.
