You are deep into the analysis phase of your Internet-accessible Student Records System (SRS). You have finished both the Functional Modeling (activity diagram, use case diagram, and use case description) and the Structural Modeling (class diagram and the CRC cards). Now you are ready to move into the Behavioral Modeling where you will model the behavior or the objects that make up the SRS system.In this week, you will use your functional and structural models as the basis for your behavioral models that need to be developed for the SRS system. Specifically, your deliverables for this week are designed to develop these two behavioral diagrams for the Register a Student for
Classes use case.

Communication diagram
In addition, you will also need to create a state machine diagram for the RegistrationRecord class (the class that maintains the registration of a student in a class).

They give you your first opportunity to verify that your use case (in this case, Register a Student for Classes) could actually be implemented using the objects of your class diagram design. If you reach this verification, then you are done with the analysis phase of your SRS project.
