Data-flow diagram or DFD is a method of representing a flow of a data of a process or a system (for example, 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.

ConceptDraw PRO software includes Data Flow Diagrams Solution for data representing in flowchart format. DFD (Data Flow Diagrams) Solution contains templates, samples and libraries of vector stencils for drawing the data flow diagrams (DFD).
