(a) TDS wants to install a system to record orders for items to be shipped. When regular customers bring in an item to a retail centre for shipping their phone number is entered into the system. The phone number invokes the customer's name, address and last order date automatically on the screen. Once the shipping order is taken the total, including tax and delivery charge is calculated. The order is then sent to the shopping area. A receipt is printed. If it is a new customer, the relevant information is recorded and stored. Occasionally, special offers (coupons) are printed so the customer can get a discount. Drivers who make deliveries give customers a copy of the receipt and coupon (if any). Weekly totals are kept for comparison with last year's performance. Draw a Level 1 diagram to represent the flow of data through the proposed system.
