Rick Williams, a systems analyst, and Carla Moore, a programmer/ analyst, completed a set of DFDs representing a data and process model of the SWL payroll system project. Rick had recently attended a workshop on object modeling techniques, and suggested that he and Carla should experiment with object-oriented analysis. After he explained the concepts and techniques to Carla, she agreed that it was a good opportunity to gain some experience, and they decided to give it a try.

1. Rick is interested in your views on the future of object-oriented analysis and design. He is scheduled to make a presentation on the topic next week at a meeting of IT professionals. He asked you to do some research, using the Internet and industry publications, and send him an e-mail message describing the current use of object-oriented analysis and trends for the future.
2. As a team member, you know how important it can be to have a well-organized object model. The team has asked you to handle this task. How will you go about it?
3. When you worked on the class diagrams, you had to understand and apply the concept of cardinality. How would you explain this concept to a new team member?
4. List all the different types of diagrams you used to create the object model, with a brief explanation of each diagram.
