a$.$ Create an ER diagram to represent the data use by the library.

The library provides books to borrowers. Each book is described by title, edition and year

of publication and is uniquely identified using the ISBN. Each borrower is described by

his or her name and address and is uniquely identified using a borrower number. The

library provides one or more copies of each book and each copy is uniquely identified

using a copy number, status indicating if the book is available for loan and the allowable

loan period for a given copy. A borrower may loan one or many books and the date each

book is loaned out and is returned is recorded. The loan number uniquely identifies each

book loan
