The following narrative describes the processing of customer mail orders at Phoenix Company.

Phoenix Company is a small manufacturing operation engaged in the selling of widgets. Customer mail orders are received in the sales order department, where sales order clerks open the orders and review them for accuracy. The clerks enter each order into the computer, where they are edited by comparing them to customer master data (stored on a disk). The computer displays the edited order on the clerk's screen. The clerk reviews and accepts the order. The order is then added to the sales event data (stored on a disk) and updates the sales order master data (also stored on a disk). As the order is recorded, it is printed on a printer in the warehouse (the picking ticket). A copy of the sales order is also printed in the sales order department and is sent to the customer (a customer acknowledgment).
