The goal of the project is to design and implement a basic media library system in which administrators (you) ean inquire the current inventory, and add or remove iteus. These items are identified either as book or smovies. The media library is organized as follows. Each entry in the library can be identified by its media type (Movie or Book), its Title, its Reference, and its Price. A sample media library comprised of 9 iteas is given in Table L. $11.99 Talble 1: A sasple media library In addition, a book media item includes information about by its Author, while a movie media iten inchudes ladoemation ahout its Direetor and Load Actoe.
