Create a Level$-0$ DFD for a public library borrowing system $($do not worry about catalogue searching, etc.$).$ The system will record the books owned by the library and will record who has borrowed what books. Before someone can borrow a book, they must show a valid id card, which is checked against the borrower database maintained by the library to ensure that it is still valid. If the would$-$be borrower does not have their library card with them, they can provide their name and address and the librarian can check that against the list of users. The system must also check to ensure the borrower does not have any overdue books or unpaid fines before he or she can borrow another book. As soon as a book becomes overdue, the system generates an automated reminder email and sends it to the borrower responsible. If a book is overdue by more than two weeks, a fine will be imposed and a librarian will telephone the borrower to remind him or her to return the book$($s$).$ Sometimes books are lost or are returned in damaged condition. The manager must then remove them from the database and will sometimes impose a fine on the borrower. Please draw and use Gane and Sarson DFD symbol set.
