Question L: Draw a use-case diagram and a set of activity dia- grams for the following system. A Video Store (AVS) runs a series of fairly standard video stores. Before a video can be put on the shelf, it must be cataloged and entered into the video database. Every customer must have a valid AVS customer card in order to rent a video. Customers rent videos for three days at a time. Every time a customer rents a video, the system must ensure that he or she does not have any overdue videos. If so, the overdue videos must be returned and an overdue fee paid before customer can rent more videos. Likewise, if the customer has returned overdue videos but has not paid the overdue fee, the fee must be paid before new videos can be rented. Every morn- ing, the store manager prints a report that lists over- due videos. If a video is two or more days overdue, the manager calls the customer to remind him or her to return the video. If a video is returned in damaged condition, the manager removes it from the video database and may sometimes charge the customer.
Question I: Draw a use-case diagram and a set of activity dia- grams for the following system. A Real Estate Inc. (AREI) sells houses. People who want to sell their houses sign a contract with AREI and provide infor- mation on their house. This information is kept in a database by AREI, and a subset of this information is sent to the citywide multiple-listing service used by all real estate agents. AREI works with two types of potential buyers. Some buyers have an interest in one specific house. In this case, AREI prints information from its database, which the real estate agent uses to
help show the house to the buyer (a process beyond the scope of the system to be modeled). Other buyers seek AREIâ€™s advice in finding a house that meets their needs. In this case, the buyer completes a buyer infor- mation form that is entered into a buyer database, and AREI real estate agents use its information to search AREIâ€™s database and the multiple-listing service for houses that meet their needs. The results of these searches are printed and used to help the real estate agent show houses to the buyer.
