TESCO – Online Shopping
TESCO Company sells its products to customers using the Internet. The general public can browse the catalogue of products contained in an inventory file. To make a purchase a new customer will enter their name and address and personal email profile. The internet user is invited to register as a customer by creating a username and password for further use of the system. The customer may proceed to add items to a shopping cart. At any point the customer can view the shopping cart list and amend its contents. When the customer is satisfied with their selection of product they will check out the order. If the customer has previously purchased goods then the system will display their credit card details and offer the customer the option of amending the card details or accepting the current details. If the customer has not previously used their credit card then they are requested to enter the card details. When the user confirms the purchase the system will create a customer order and issue their credit card details to a third party organization to validate the credit card account and process the payment. The system will send a copy of the customer order to shipping department who will fulfill the purchase and dispatch the goods to the customer.
