In Chapter 3, you identified use cases for the business events for the Community Board of Realtors. In Chapter 5, you elaborated on those use cases. In Chapter 4, you identified the classes associated with the business events. Using your solutions from those chapters, develop:

1. A first-cut DCD by using the problem domain classes that you identified in Chapter 4.
2. A communication diagram for the Create new listing use case (domain classes and controller class only).
3. A sequence diagram for the Update agent information use case (domain classes and controller class only).
4. A separate multilayer sequence diagram for the Update agent information use case that includes the domain classes and the view layer classes.
5. A final design class diagram that includes the classes from both use cases. Include elaborated attributes, navigation arrows, and all the method signatures from both use cases.
