Section C – Modelling Questions (40 Marks) Read the following case study carefully: UsedBooksMarketPlace.com is an online company that facilitates business exchange between buyers and sellers of used books. In order for a seller to offer books for sale, she must register with UsedBooksMarketPlace.com. The seller must provide a current physical address and telephone number as well as a current email address. The system will then maintain an open account for this seller. Access to the system as a seller is through a secure, authenticated portal. A seller can list books on the system through a special Internet form. Information required includes all of the pertinent information about the book, its category, its general condition, and the asking price. A seller may list as many books as desired. The system maintains an index of all books in the system so that buyers can use the search engine to search for books. The search engine allows searches by title, author, category, and keyword. People desiring to buy books get onto the website and search for the books they want. When they decide to buy, they must open an account with a credit card to pay for the books. The system maintains all of this information on secure servers. When an order is placed, along with the payment, this order is given an “open” status, and UsedBooksMarketPlace.com sends an email notice to the seller of each book that was chosen. It also marks the book as sold. Once the seller receives notice that a listed book has been sold, she must notify the buyer, via email within 48 hours that the purchase is noted. Shipment of the order must be made with 24 hours after the seller sends the notification email. The seller sends a notification to both the buyer and UsedBooksMarketPlace.com when the shipment is made. After receiving notice of shipment, UsedBooksMarketPlace.com moves the order to a “shipped” status. At the end of each month, a check is mailed to each seller for all of those book orders that have been in a “shipped” status for thirty days. The thirty-day wait is to allow the buyer to notify UsedBooksMarketPlace.com for any problems with the order, e.g. if for some reason the shipment does not arrive, or if the book is not in the same condition as advertised. The buyers can, if they desire, enter a seller satisfaction code for the seller. The seller satisfaction code is an indication of how well the seller is handling book purchases. Some sellers are very active and use UsedBooksMarketPlace.com as a major outlet for selling books. So a seller satisfaction code is an important indicator to potential buyers. Based on the scenario provided answer the following questions. C.1.

Draw an entity relationship diagram for the case study above.
