The data flow diagram of the proposed system shows the flow of data between the different components of the system. The system is composed of four main components: the customer, the KFC staff, the food ordering process, and the payment system.
The customer places an order for food through the food ordering process. The food ordering process then sends the order to the KFC staff. The KFC staff then prepares the food and delivers it to the customer. The customer then pays for the food through the payment system.
The data flow diagram shows the flow of data between these four components. The arrows in the diagram represent the flow of data. The data that flows between the components is represented by the text labels on the arrows.
The data flow diagram is a useful tool for understanding the flow of data through a system. It can be used to identify potential problems in the system and to improve the efficiency of the system.
