E-mail, Password, Credit Card: Creating a Customer Profile

E mail, Password, Credit Card Creating a Customer Profile

The goal for this iteration is to complete the online ordering process by implementing the code to collect the necessary customer information. Also, we want to store this information in a database for later use. But before we start the implementation, we need to know exactly what information will be collected and which forms we will use.

12.3.1 User Interfaces

After online customers have put items into their shopping cart, they can proceed to the checkout procedure. This area of Online Photo Shop will require a login step to identify the customer. We need this identification to make sure that we do not display someone's payment information to any third party. Also, new customers can use the login page to register themselves using their e-mail address and a password. Figure 12.1 shows the sketch of the login page.

After a customer is logged in, the shipping and payment information is collected for new customers, or verified for returning customers. This can actually be done on the same page. For returning customers, however, by default the fields will be set to the information used for the most recent order. Figure 12.2 shows the layout of the checkout form.

12.3.2 Database Records

The data fields shown in Figures 12.1 and 12.2 also help to define the customer profile that will be stored in the customer database. Table 12.2 summarizes all fields and their types.

12.3.3 Tax and Shipping

Before an order can be completed, we need to compute the total cost, including shipping and sales tax if applicable. The business is a New Jersey-based company, so sales tax applies only to customers with NJ residences. The sales tax in New Jersey is 6%.

Only one shipping method is offered at this time. The cost of shipping consists of a fixed base amount of $1.25 plus $3.00 per pound.

12.3.4 Finalizing an Order

The requirement key F:checkout_summarize requires the Online Photo Shop application to make the information for each completed order available to order processing. We decide to use structured text files in XML format to make this information accessible to other applications. This XML file will contain the complete customer record, including shipping address and payment entered at the time of the order. Furthermore, the total amount of the order will be provided along with the amounts for shipping and sales tax. Next, all items ordered will be stored along with the file name of the uploaded digital picture for customizations. Such a file is shown in Listing 12.1.
