User Stories – Book Shop
The manager of a small book shop has asked you to design and implement a database that centralizes information so that it is easier and more efficient to man-age inventory and track orders and sales. The shop handles rare and out-of-print books and tends to carry only a few thousand titles at any one time. Currently, the manager tracks all of the sales and inventory on paper. For each book, the manager records the title, author, publisher, publication date, edition, cost, suggested retail price, and a rating that indicates the condition of the book. Each book is assigned one of the following ratings: superb, excellent, good, fair, poor, or damaged. The manager would like to be able to add a description to each rating (just a couple of sentences), but the description should not be required.

Because these books are rare, each title must be tracked individually—even if they are the same book (identical title, author, publisher, publication date, and edition).
