About This Architecture

Library Management System use case diagram models three user roles—Student, Librarian, and Admin—interacting with core system functions. Students perform self-service operations: Search Book, Borrow Book, Return Book, and Register User, while Librarians handle Approve Borrow Request and Manage Inventory tasks. Admins oversee Manage User Accounts and Configure System functions, establishing clear role-based access control. This use case structure demonstrates separation of concerns and principle of least privilege, critical for secure, maintainable library platforms.
