Data Flow Diagram (DFD)

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

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 Model

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

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.

Types of Flowcharts

A Flowchart is a graphically representation of the process, algorithm or the step-by-step solution of the problem. There are ten types of Flowcharts. Using the Flowcharts solution from the Diagrams area of ConceptDraw Solution Park you can easy and quickly design the Flowchart of any of these types.

Context Diagram Template

This template shows the Context Diagram. It was created in ConceptDraw PRO diagramming and vector drawing software using the Block Diagrams Solution from the “Diagrams” area of ConceptDraw Solution Park.
The context diagram graphically identifies the system. external factors, and relations between them. It’s a high level view of the system. The context diagrams are widely used in software engineering and systems engineering for designing the systems that process the information.

DFD Library System

Use the Data Flow Diagrams solution from the Software Development area of ConceptDraw Solution Park to draw your own context-level DFDs using the ConceptDraw PRO diagramming and vector drawing software.

Interaction Overview Diagram

UML Interaction Overview Diagram schematically shows a control flow with nodes and a sequence of activities that can contain interaction or sequence diagrams.

Use Case Diagrams technology with ConceptDraw PRO

Use case diagrams are used at the development of software and systems for definition of functional system requirements or system of systems. Use case diagram presents the consecution of object’s actions (user’s or system’s) which are executed for reaching the definite result.

Data Flow Diagrams

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