  • Data-flow diagram - Wikipedia

    A data-flow diagram is a way of representing a flow of data through a process or a system (usually an information system).The DFD also provides information about the outputs and inputs of each entity and the process itself. A data-flow diagram has no control flow — there are no decision rules and no loops. Specific operations based on the data can be represented by a flowchart.
