Extracted text: CASE STUDY 2 Draw appropriate DFD Level O for the following case study. State any assumption for the diagram. UMSKAL Beach Café wants to install a system to record orders for nasi Kerabu, nasi Tomyam and Cendol. When regular customers aka students of UMSKAL call UMSKAL Beach Café on the phone, they are asked their matric number. When the matric number is typed into a computer, the name, address, and last order date is automatically brought up on the screen. Once the order is taken, the total, including delivery, is calculated. Then the order is given to the cook. A receipt is printed. 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 a coupon (if any). Weekly totals are kept for comparison with last year's performance.
