A library has books, videos, and CDs that it loans to itsusers. All library material has an id# and a title. In addition, books have one or more authors,videos have one producer and one or more actors, while CDs have one or more entertainers. Thelibrary maintains one or more copies of each library item (book, video or CD).Copies of all library material can be loaned to users. Reference-only material is loaned for 2hrsand can't be removed from the library. Other material can be loaned for 2 weeks. For every loan,the library records the user, the loan date and time, and the return date and time. For users, thelibrary maintains their name, address and phone number.
