Scenario:
A city Library needs an information system to maintain the
information on their books, members and transactions efficiently.
Some of the database requirements are as follow:
· Information
stored about books include unique ID, title, ISBN, publication
year, author and publisher.
· A book might
have many copies and a copy belongs to exactly one book. Each copy
of a book is uniquely identified by copy ID and book ID.
· A book is
written by one or many authors. An author is characterized by
author ID name and date of birth.
