Explain the purpose of the class diagram and why is it important to identify class early in the Unified Process methodology?

Solution

In Class Diagram, we represent the system classes and their relation with each other, it represent the static view of an application. It helps in documenting, visualaizing different aspects of the system as well as help us to construct the executable codes. Other Unified Methodology Diagram helps in understanding the sequence flow of the application(which event will cause the triggering of which event like sequence only). Class Diagram is the important one due to followin reasons.

1. By Class Diagram, we can define responsibilities of application.

2. Class Diagram used for forward and reverse engineering.

3. Class Diagram used to develop component and deployment diagram.
