A Data Flow Diagram (DFD) is a graphical representation of the flow of data through an information system. It uses only four symbols to show the logical design of the system, which are: circles to represent processes, arrows to represent data flow, open-ended rectangles to represent sources and sinks of data, and closed-ended rectangles to represent data stores. DFDs are used by systems professionals to analyze, design, and document information systems.
