10 A Library lends books and magazines to member, who is registered in the system. It also maintains
the purchase of new books andmagazines for the Library. A member can reserve a book ormagazine
that is not currently available in the library, so that when itis returned or purchased by the library,
that person is notified.The library can easily create, replace and delete information aboutthe books,
members, and reservation in the system. Thebooks transactions are stored in the database. The fine
list while themember returns the book after the due date must be generated.Design the use case
diagram and discover the users and actors ofthis system, and the interactions between them must be
depicted.
