Semantics Limited is a manufacturer of revolutionary glass windows that are fog and dirt Summise Inc. offers a hire service to customers, with customers hiring electronic photographic equipment for personal and professional uses. The hiring process is described below. The client sends in a hire request form, which is received by the hire consultant. The hire consultant enters the customer name into the computer and the computer retrieves the customer address from the customer data file and checks the accounts receivable data to ensure no outstanding invoices are owed by the customer. This data is displayed on the computer screen. The item numbers for the products that the customer wishes to hire are keyed in, with the computer retrieving the product description from the equipment data file. The complete order details are displayed on the computer screen and the hire consultant checks that the details match those on the request form. If they agree then the 'confirm order' button is clicked and the data saved in the 'hire orders' data file. The paper hire request form is filed by customer name. When the computer gets the confirmation of the order from the hire consultant it emails a copy of the hire order form to the inventory control assistant. The order is printed out and the assistant gets the goods listed and packs them securely for sending to the customer. Once the goods are packed, the assistant goes to the computer and enters the hire order form number, with the computer retrieving the full details from the 'hire orders' data file. The assistant then enters their name and the date the goods were packed. The computer then saves these full details in the invoice file and prints a copy of the invoice and the customer insurance policy. The invoice is attached to the goods and they are sent to the customer at 4 pm each day. At 6 pm each day, once the trading hours for the business are complete, the computer then accesses the invoice data file and takes the data for all invoices created on that day and updates the sales data, accounts receivable data and the inventory availability data. The paper copy of the hire order form is signed by the assistant who packed the goods and then filed by date in the inventory on loan file.
