Singleton Product Offering (SPO) is a start-up, offering unique, one-of-a-kind products to customers through an online system. You were hired to perform systems analysis and design work for this initiative. Here is some information available to you:

2. Customers will get into the website using a URL.

3. Customer may leave the site at any time. Last visit info will be kept in the system using cookies.

Guest customers will be directed to the data entry screen where the customer will provide personal information (first name, last name, phone, home address, shipping address), email, and credit card info (name on card, card number, expiry date, and CVV).
