Data Flow Diagram (DFD)

This example is created using ConceptDraw DIAGRAM enhanced with solution Data Flow Diagrams. This diagram shows one of the business processes to simplify and accelerate understanding, analysis, and representation.

Data Flow Diagrams

ConceptDraw DIAGRAM software enables you to quickly create data flow diagrams that include data storage, external entities, functional transforms, data flows, and control transforms and signals.

Data Flow Diagram Symbols. DFD Library

Data Flow Diagrams show information transfers and process steps of a system. The general concept is an approach of a depicting how occurs input in a system, further processes and what runs out. The aim of DFD is in accomplishing of understanding between developers and users. Data flow diagrams are maintained with other methods of structured systems analysis.

Data Flow Diagram

Data flow diagram (DFD) is the part of the SSADM method (Structured Systems Analysis and Design Methodology), intended for analysis and information systems projection. Data flow diagrams are intended for graphical representation of data flows in the information system and for analysis of data processing during the structural projection. Data flow diagram often used in connection with human process and can be displayed as workflow diagram. The critical Process Flow Diagram is another flowchart technique for designing data flow in connection with organizational processes. The critical Process flow diagram may use different range of symbols than a classic workflow diagram.

Example of DFD for Online Store (Data Flow Diagram)

Data flow diagrams (DFDs) reveal relationships among and between the various components in a program or system. DFDs are 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.
Example of DFD for Online Store shows the Data Flow Diagram for online store and interactions between the Visitors, Customers and Sellers, as well as Website Information and User databases.

Data Flow Diagram Model

The DFD (Yourdon and Coad notation) example "Model of small traditional production enterprise" below was created using the ConceptDraw DIAGRAM diagramming and vector drawing software extended with the Data Flow Diagrams solution from the Software Development area of ConceptDraw Solution Park.

Data Flow Diagrams

Data Flow Diagrams (DFDs) are graphical representations of the "flow" of data through an information system. Data flow diagrams can be used for the visualization of data processing. ConceptDraw DIAGRAM extended with Data Flow Diagrams Solution is a powerful data flow diagramming application that allows you quickly create any Data Flow Diagrams including the data storages, external entities, functional transforms, data flows, as well as control transforms and signals.
