DRAW THE E-R DIAGRAM LISTING ENTITIES, ATTRIBUTES AND RELATIONSHIPS FOR THE FOLLOWING SCENARIO:
A county wishes to create a database to control its local libraries. Each library has a number of employees, one of whom is designated as the manager of the library and is responsible for supervising employees and the general day-to-day management of the library.
Each library stores a number of books and CDs. A citizen has to become a member of a library before he/she is allowed to borrow any books, but thereafter can borrow books from any county library. Generally, a library stocks a number of copies of each book title and each CD. Details of books publishers are maintained but not CD publisher.
Can you provide the answer as soon as possible and there is no word limit?
