A data flow diagram (DFD) is a visual representation of the flow of information within a system or process. It uses symbols like rectangles, circles, and arrows to show data inputs, outputs, storage points, and the routes between each destination. DFDs can be used to analyze existing systems or model new ones. They are helpful for both technical and non-technical audiences as they can visually represent complex information in an easy-to-understand manner.
Would you like me to create a DFD for you? If so, please provide more details about the information system you would like to represent.
