Exercise 1: Library Management System Design a Data Flow Diagram (DFD) for a Library Management System. In this system, a Librarian is responsible for managing the library's book inventory, including adding new books, updating details of existing books, and removing books when necessary. Members of the library can search for books based on various criteria, borrow books, and return them when they are done. The system should maintain a record of all available books and members. Additionally, the librarian should be able to view reports on the borrowing and returning activities of members. Create a Level 0 and Level 1 DFD to illustrate these interactions.
