A data flow diagram (DFD) is a useful tool for visualizing the flow of data in a system. In a shopping scenario, a DFD could illustrate the steps involved in creating a shopping list, looking up barcode prices, calculating the total price, and issuing a receipt to the customer. The DFD would include processes such as inputting items into the shopping list, scanning barcodes to obtain product information and prices, and performing calculations to determine the total cost of the purchase. The diagram would also show the flow of data between these processes, including the transfer of information from the shopping list to the barcode scanner and from the barcode scanner to the calculation process. Finally, the DFD would illustrate the output of the system, including the printing of the receipt for the customer. By creating a clear and concise DFD, developers can better understand the flow of data in the shopping system and ensure that it is designed to meet the needs of both customers and business owners.
