Create a set of detail use case descriptions and draw a use-case diagram for a university library borrowing system (do not worry about catalogue searching, etc.). The system will record the books owned by the library and will record who has borrowed which books. Before someone can borrow a book, he or she must show a valid ID card, which is checked against the student database maintained by the registrar's office (for student borrowers), the faculty/staff database maintained by the personnel office (for faculty/staff borrowers), or against the library's own guest data base (for individuals issued a guest card by the library) to ensure that it is still valid.
The system must also check to ensure that the borrower does not have any overdue books or unpaid fines before he or she can borrow another book. The library prints and mails postcards to those people with over due books. If a book is overdue by more than two weeks, a fine will be imposed and a librarian will telephone the borrower to remind him or her to return the book(s). Sometimes books are lost or are returned in damaged condition. The manager must then remove them from the database and will sometimes impose a fine on the borrower.? Please make sure to use the use case description template available on the web site and the guidelines discussed in class.
