THE REAL ESTATE MULTIPLE LISTING SERVICE SYSTEM The Real Estate Multiple Listing Service system supplies information that local real estate agents use to help them sell houses to their customers. During the month, agents list houses for sale (listings) by contracting with homeowners. The agent works for a real estate office, which sends information on the listing to the multiple listing service. Therefore, any agent in the community can get information on the listing. Information on a listing includes the address, year built, square feet, number of bedrooms, number of bathrooms, owner name, owner phone number, asking price, and status code. At any time during the month, an agent might directly request information on listings that match customer requirements, so the agent contacts the multiple listing service with the request. Information is provided on the house, on the agent who listed the house, and on the real estate office for which the agent works. For example, an agent might want to call the listing agent to ask additional questions or call the homeowner directly to make an appointment to show the house. Twice each month (on the 15th and 30th), the multiple listing service produces a listing book that contains information on all listings. These books are sent to all of the real estate agents. Many real estate agents want the books (which are easier to flip through), so they are provided even though the information is often out of date. Sometimes agents and owners decide to change information about a listing, such as reducing the price, correcting previous information on the house, or indicating that the house is sold. The real estate office sends in these change requests to the multiple listing service when the agent asks the office to do so. Chapter 7 â€“ Pick 2 from the 4 below. Using the event list and ERD for that system as a starting point, develop the following object-oriented models: 1. Convert your ERD to a domain class diagram. 2. Develop a use case diagram. 3. Create a fully developed use case description or an activity diagram for each use case. 4. Develop a system sequence diagram for each use case. Chapter 8 â€“ Pick 1 from below Consider the requirements of the multiple listing service system developed in Chapters 5, 6, and 7. Assume that youâ€™re the project manager and that you work for a consulting firm hired by the multiple listing service to perform only the survey and analysis activities. 1. Assume that system users and owners have indicated a strong desire for a system that can be accessed â€œanytime, anywhere.â€ Discuss the implications of their desire for the system scope. Given the preferences of the system users and owners, should you prepare a table similar to Figure 8-2? Why or why not? 2. Discuss the implications of the anytime, anywhere requirement for the application deployment environment. What type(s)of hardware, network, and software architecture will be required to fulfill that requirement? 3. Investigate the availability of packaged and turnkey systems for multiple listing services. Search the Internet and real estate trade magazines and Web sites. Discuss the pros and cons of choosing a packaged or turnkey system. 4. Develop an RFP outline that covers packaged, turnkey, and custom-developed systems. What are the difficulties of writing one RFP that covers all three scenarios? Who should be involved in evaluating RFP responses? THE STATE PATROL TICKET PROCESSING SYSTEM The purpose of the State Patrol ticket processing system is to record driver violations, to keep records of the fines paid by drivers when they plead guilty or are found guilty of moving violations by the courts, and to notify the court that a warrant for arrest should be issued when such fines are not paid in a timely manner. A separate State Patrol system records accidents and verification of financial responsibility (insurance). Yet a third system produces driving record report
