We need to design a software system to help in library management. The system should store locations of books and their quantities according to book classification standards. System should keep track of library members loans. Loans could be of different types ranging from one hour till one month, depending on the rank of the member and availability of the book. Library members could be faculty staff, students, or people from the community. People from community should pay annual fees in cash or by credit card or by bank deposit. Library could contact other libraries to exchange books. Library could contact book stores, publishers and charity organizations for buying books and getting discounts. Library has printing facilities, members pay for such services per use by credit. This credit should be paid in a monthly manner, otherwise membership will be cancelled. Of course, the system should keep track of library staff information, their working shifts, all financial transactions, and books inventory. Also it should allow searching for books in different ways, also library members could recommend books for the library; they also could donate books to the library. The system should also manage the cultural events (such as raising funds, book signing events, and seminars) organized by the library and their financial records. Some seminars are for free others for a small fee. The system should be web enabled and available all week days.
