Design a Library Management System A Library Management System is an example of an information system built to handle the primary functions of a library. In this Library Management System project, you can enter the record of new books and retrieve the details of books available in the library. You can issue the books to the students and maintain their records. Late fine is charged for students who returns the issued books after the due date. System Requirements Keep in your consideration the following set of requirements while designing the Library Management System: 1. Any library member should be able to search books by their title, author, subject category as well by the publication date. 2. Each book will have a unique identification number and other details including a rack number which will help to physically locate the book. 3. There could be more than one copy of a book, and library members should be able to check-out and reserve any copy. We will call each copy of a book, a book item. 4. The system should be able to retrieve information like who took a particular book or what are the books checked-out by a specific library member. s. There should be a maximum limit (2) on how many books a member can check-out. 6. There should be a maximum limit (2 weeks) on how many days a member can keep a book. 7. The system should be able to collect fines for books returned after the due date 8. Each book and member card will have a unique barcode. The system will be able to read barcodes from books and members' library cards We have two main actors in our system: - Librarian: Mainly responsible for adding and modifying books, book items, and users. The Librarian can also issue and return book items. - Member: All members can search the catalog, as well as check-out, renew, and return a book. Here are the top use cases of the Library Management System: Add/Remove/Edit book: To add, remove or modify a book or book item. Add/Remove/Edit book: To add, remove or modify a book or book item. Search catalog: To search books by title, author, subject or publication date. Register new account/cancel membership: To add a new member or cancel the membership of an existing member. . Check-out book: To borrow a book from the library. Renew a book: To reborrow an already checked-out book. Return a book: To return a book to the library which was issued to a member Here are the main classes of our Library Management System: Book: The basic building block of the system. Every book will have ISBN, Title, Subject, Publishers, etc. BookItem: Any book can have multiple copies, each copy will be considered a book item in our system. Each book item will have a unique barcode. Account: We will have two types of accounts in the system, one will be a general member, and the other will be a librarian. LibraryCard: Each library user will be issued a library card, which will be used to identify users while issuing or returning books. BookLending: Manage the checking out of book items
