AlS outdoor is a retail business selling outdoor entertainment goods such as tents, sleeping bags, camping furniture, etc. In addition to havipg stores across Australia, AIS uses a website to sell goods online. In order to buy, online customers must have previously registered and created a customer account with a unique username and password. Process 1.0 Process the sales order Customers log on to the AIS website using their registered username and password. The computer checks that the username and password are valid. Customers with an invalid username and/or password are sent a message advising them that their login is invalid. Customers with a valid username and password are presented with the current product catalogue. The customer browses the online catalogue and creates an order by entering the quantity required in a check box beside each product they want to purchase. After browsing and selecting all their products, the customer clicks an "order completed button". A total price is calculated for the goods selected based on quantity x price (a defaultsales price is stored in the inventory data store). The computer identifies suitable shipping opticns and their associated prices and presents these shipping options to the customer, along with the total price for selected products. The customer selects their preferred shipping option by checking the appropriate tick box. The computer assigns the next sales order number from the sales order data store, updates the inventory database to show that the products selected have been allocated to a sales order, then calculates a total for the sales order including the selected shipping costs. The computer saves the sales order in the sales order data store with a status ' 1 ' (awaiting payment), then displays the sales order
