Eagle Promise Library carries many book titles, sometimes
multiple copies of a title. For each title, the author(s), and call
number are also recorded. The library will loan as many as five
books to anyone with a borrower's card. Information kept on each
loan is the book title, the specific copy lent, the borrower and
the due date.
Draw an ER diagram data model for this library system, showing
relationships with minimum and maximum cardinalities.
Also, list the fields in each database table, indicating the
primary and foreign key fields.
Also include any (reasonable) assumptions you make.
