Design Library Management System

Requirements Definition

The Library Management System should support the following core features:

• Book Catalog Management: Librarians can add, update, and remove books from the catalog.
• Book Search: Users (members and librarians) can search for books by title, author, or ISBN.
• Borrowing and Returning Books: Members can borrow available books and return them. The system should enforce a limit on the number of books a member can borrow at once.
• User Management: Librarians can register new members and manage their accounts.
• Transaction Tracking: The system records each borrowing and returning event for audit and tracking purposes.
• Fine Calculation: The system calculates overdue fines for late returns.
• Role-Based Access: Members and librarians have different permissions in the system.
• Notifications: Members receive reminders for due dates and notifications for overdue books.

Non-functional requirements:

• The system should be easy to use for both librarians and members.
• The system should support a moderate number of users and books (e.g., a small to medium-sized library).
