Question

You are going to develop a software application for administering the lending of books at a public library in San Antonio. A person must be a member of the San Antonio's library and must be in good standing - that is, not any any outstanding fines or overdue books - to borrow books. A book may be borrowed up to three weeks at a time. A book loan may be renewed if the book is returned before the loan's due date and if no other library member has requested the book. If a book is returned after the loan's due date, the borrower will be charged a fine of half a dollar for each late day. Fines are paid to the library staff at the circulation desk, where books are returned. A library member can use any computer to log on to the system by entering his or her user ID and password, to search for books, to request to reserve books, and to renew book loans. The system will authenticate the member and check his or her standing before processing book search, book reservation, and book renewals. Suppose you are going to use layered style of architecture to design the library system. Provide an architecture design diagram for the library system to show the layers and the communications among layers. Name each layer and the sub-components in each layer.

The Circulation staff greets and directs visitors, answers and refers incoming phone calls to the appropriate library extensions, and accepts deliveries and donations.
