This Data Flow Diagram (DFD) for a Restaurant Ordering System is designed to visually model the processes and information exchange from customer order placement to food delivery. It is a critical analytical tool for system analysts, software engineers, and restaurant operations managers. Users begin the workflow when the Customer sends an Ordered Food request to the Food Ordering Process. Data then flows to the Payment System which generates an Invoice for bill payment and records Payment Details. The process is completed as the Food Delivering System sends the Food Delivered confirmation back to the Customer. The final DFD provides a clear, documented view of the system's operational logic, ensuring efficient order processing and accurate inventory management.
