Data Flow Diagrams (DFD)

The use of Data Flow Diagrams (DFD) solution as an extension to the ConceptDraw DIAGRAM tool can simplify its users’ work by creating any necessary Data Flow Diagram, which can help simulate multiple data flows and illustrate the functional requirements of the system or business process. Using the pre-made templates and samples of the DFDs, and as the stencil libraries full of DFD-related design elements, any ConceptDraw DIAGRAM user might find the Data Flow Diagrams (DFD) solution a useful tool for making the needed DFD drawings.

DFD Library — Design elements

Data Flow Diagrams (DFD) solution from the Software Development area of ConceptDraw Solution Park provides plenty of predesigned templates, samples and DFD vector design elements proposed by three DFD libraries. These DFD library objects are designed to help you effectively model the data flows and functional requirements for the business processes or systems, to design the Process-oriented models or Data-oriented models, Data flowcharts and Data process diagrams, Structured analysis diagrams and Information flow diagrams. There are two different notations used to draw the Data Flow Diagrams (Yourdon & Coad and Gane & Sarson). These notations define the different visual representations for the processes, data stores, data flows, and external entities. ConceptDraw DIAGRAM software provides you with possibility of designing professional-looking Data Flow Diagrams, DFD Models, Data Flow Process Diagrams using any of these notations. Simply drag the predesigned DFD flowchart symbols from the appropriate library and connect by arrows depicting the data flow from one step to another.

Data Flow Diagram Examples

Data flow diagrams (DFDs) are effective to reveal relationships among the various components in a program or system. This type of diagrams is an important and useful technique for modeling an information system, its process aspects, for showing a system as a single high-level process. DFD lets illustrate the flow of data, how the input data are transformed to output results across the sequence of functional transformations. DFD consists of four major components: entities, processes, data stores, data flows. When you need to draw a Data Flow Diagram the ConceptDraw DIAGRAM diagramming and vector drawing software extended with Data Flow Diagrams solution will be helpful for you. Providing numerous collection of Data Flow Diagram examples, samples, templates and ready-to-use vector DFD symbols, Data Flow Diagrams solution ensures you with all needed tools for easy designing DFDs according to Gane-Sarson or Yourdon-Coad notation on your choice. Any from offered predesigned DFD examples can become a perfect base for your own diagram.

Data Flow Diagram Symbols. DFD Library

Data Flow Diagrams graphically represent the information transfers and process steps of a system. They visually depict how data are processed by a system in terms of inputs and outputs, how occurs the input in a system, how the data flow through an information system and where they are stored, and how occurs output from the system. DFDs give the overview of the system and models the processes aspects, they are maintained with other methods of structured systems analysis. The main goal of DFDs is achievement of understanding between developers and users. For their construction are used two notations - Gane-Sarson and Yourdon, each of them uses its own set of symbols. Data Flow Diagrams solution from Software Development area extends the ConceptDraw DIAGRAM software with templates, samples, and predesigned libraries of data flow diagram symbols for both notations, allowing you easy design the process-oriented and data-oriented models, draw the Data Flow Diagrams, Data Flowcharts, Data Process Diagrams, Information Flow Diagrams, Structured Analysis Diagrams, etc.

DFD - Process of account receivable

"Data flow diagrams are one of the three essential perspectives of the structured-systems analysis and design method SSADM. The sponsor of a project and the end users will need to be briefed and consulted throughout all stages of a system's evolution. With a data flow diagram, users are able to visualize how the system will operate, what the system will accomplish, and how the system will be implemented. The old system's dataflow diagrams can be drawn up and compared with the new system's data flow diagrams to draw comparisons to implement a more efficient system. Data flow diagrams can be used to provide the end user with a physical idea of where the data they input ultimately has an effect upon the structure of the whole system from order to dispatch to report. How any system is developed can be determined through a data flow diagram model.
In the course of developing a set of levelled data flow diagrams the analyst/ designers is forced to address how the system may be decomposed into component sub-systems, and to identify the transaction data in the data model.
Data flow diagrams can be used in both Analysis and Design phase of the SDLC.
There are different notations to draw data flow diagrams (Yourdon & Coad and Gane & Sarson), defining different visual representations for processes, data stores, data flow, and external entities." [Data flow diagram. Wikipedia]
The DFD (Yourdon and Coad notation) example "Process of account receivable" 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.
