You have been handed the following system description and requirements to build a Book Auction website:

The users of the system are buyers, sellers, and admins

Buyers and sellers must create an account in order to use the system

During account registration, the buyer and seller must provide the following information:

first name and last name

postal address

email address

Upon registration, the admin must verify all the new users. After users are verified, buyers and sellers can then buy or sell books through the Book Auction. The users must first log-in the system to be verified before they are authorized to sell or buy a book.

For each book the seller wants to sell, he/she must post the following information on the website:

title of the book

author(s) of the book

publication year of the book

starting price of the book

book condition (new, used)

an image of the books cover page

auction bidding time span in days

When a buyer searches for books, he/she can select an individual book

Buyers can bid on a selected book

If the buyer wins the auction, he/she is obligated to order the book

The order is considered completed when the payment is completed. If the payment is not completed the order will remain incomplete. Each order can only have one book in it, so each book must be paid separately (no shopping cart here)

To complete the purchase, the buyer must provide a valid credit card:

credit card number

expiration date

security code

The pay process will be handled by an external payment system (such as PayPal)
