library information system:

Consider the following university library borrowing information system. The system maintains a database of books owned by the library and the transaction (borrowing and returning) details of library patrons. Before someone can borrow a book, he or she must show a valid ID card that is checked to ensure that it is still valid using the student database maintained by the registrars office (for student borrowers), the faculty/staff database maintained by the personnel office (for faculty/staff borrowers), or against the librarys own guest database (for individuals issued a guest card by the library). The system also checks to ensure that the borrower does not have any overdue books or unpaid fines before he or she can borrow another book. Every Monday the library prints and mails letters to those people with overdue books. If a book is overdue by more than two weeks, a fine will be imposed and 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 librarian must then remove them from the database and will sometimes impose a fine on the borrower.
