By mapping out your process or system's flow of data, dfds help you better understand.
The dfd also provides information about the outputs and inputs of each entity and the process itself.
15 Data Flow Diagram. A data flow diagram (dfd) is a graphical representation of the flow of data through an information system (as shown on the dfd flow chart figure 5), modeling its process aspects. Quickly learn data flow diagram (dfd). Data stores — where information is stored within the system. Data stores are notated as rectangles with two parts, such as supplier details and orders in the example above.
