How to Create a Data Flow Diagram using ConceptDraw PRO

ConceptDraw Data Flow diagram (DFD) example

Data flow diagramming is a highly effective technique for showing the flow of information through a system. Data flow diagrams reveal relationships among and between the various components in a program or system. DFD is an important technique for modeling a system’s high-level detail by showing how input data is transformed to output results through a sequence of functional transformations. The set of standard symbols is used to depict how these components interact in a system. ConceptDraw PRO allows you to draw a simple and clear Data Flow Diagram using special libraries.
