Data Flow Diagram (DFD) is a hierarchy of functional processes, connected by data flows. The purpose of this presentation is to show how each process converts its inputs into outputs and to identify relationships between these processes. DFD is convenient way of modeling and construction the information processes, it step-by-step illustrates the flow of information in a process. For construction a DFD traditionally are used two different notations, which appropriate to the methods of Yourdon-Coad and Gane-Sarson. These notations slightly different from each other by graphical representation of symbols for processes, data stores, data flow, external entities. When designing a DFD it is required to decompose the system into the components (sub-systems), for explaining a complex system you may need represent numerous levels.
The Data Flow Diagrams solution from ConceptDraw Solution Park contains numerous predesigned DFD symbols for both notations, which help easy and effectively design professional-looking Data Flow Diagrams (DFDs) and DFD Process Diagrams. Read more

Use of Cross-Functional Flowchart is a clear way of showing each team member’s responsibilities and how processes get shared or transferred between different responsible people, teams and departments. Use the best flowchart maker ConceptDraw PRO with a range of standardized cross-functional flowchart symbols to create the Cross-Functional Flowcharts simply and to visualize the relationship between a business process and the functional units responsible for that process.
To draw the most quickly Cross-Functional Flowcharts, Cross Functional Process Maps, or Cross Functional Process Flow Diagrams, start with a Cross-functional flowchart samples and templates from ConceptDraw Solution Park. The ConceptDraw Arrows10 and RapidDraw technologies will be also useful for you in drawing. ConceptDraw PRO supports designing both types - horizontal and vertical Cross-functional flowcharts. A vertical layout makes the accents mainly on the functional units while a horizontal layout - on the process.
If you need a Visio alternative in Mac OS X, try ConceptDraw PRO. Its interface is very intuitive and it’s actually much easier to use than Visio, yet somehow it’s just as powerful if not more so. ConceptDraw PRO performs professional quality work and seamless Visio interaction. Read more
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 PRO 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. Read more
Data flow diagram or DFD is a type of diagrams used for graphical representation the "flow" of data through an information system, for effective modeling its process aspects and for visualization the data processing. They are one of the best tools for clearly making an overview of the system that will be developed, for depiction in details what kinds of information will be inputted to the system and outputted from it, where they will be stored, and other details.
ConceptDraw PRO software with Data Flow Diagrams solution from Software Development area of ConceptDraw Solution Park is powerful in a field of designing the DFDs. Three libraries containing 49 vector DFD shapes and symbols are offered by Data Flow Diagrams (DFD) solution. Use them to design data flow diagrams, information flow diagrams, data flowcharts, data process diagrams, structured analysis diagrams, to create the data-oriented models or process-oriented models, and so on. Pay also attention for the included collection of DFD samples, examples and built-in templates at ConceptDraw STORE. Read more

A Data Flow Diagram (DFD) illustrates the flow of data through an information system, visualizes how the information is handled in terms of inputs and outputs, how the data enter to system and leave it. It is effective to use a Data Flow Diagram for creation the system's overview, to show the system's scope and boundaries. There are two different types of notations for DFDs: Yourdon-Coad and Gane-Sarson, which differ in visual representations for processes, data flow, data stores, external entities, etc. Thus, for example the processes are depicted as circles in Yourdon-Coad notation and as rounded squares in Gane-Sarson notation. Gane-Sarson notation is usually used for visualization information systems and Yourdon-Coad - for system analysis and design.
The Data Flow Diagrams solution included to Software Development area of ConceptDraw Solution Park offers a lot of DFD templates, samples and examples, libraries of vector stencils for construction without efforts the DFDs according to both Gane-Sarson and Yourdon-Coad notations. Read more
The Data Flow Diagram (DFD) is a graphical technique used for effective modeling and analyzing the information processes and systems. Having at the disposal the DFD library system and newest powerful tools of ConceptDraw PRO diagramming and vector drawing software supplied with Data Flow Diagrams (DFD) solution from the Software Development area of ConceptDraw Solution Park, you can design fast and easy the Data flow diagrams, Data flowcharts, Data flow models, Data flow process diagrams, Process-oriented models, Data-oriented models, Data process diagrams, Structured analysis diagrams, Information flow diagrams of any type and complexity. For designing the Data Flow Diagrams in ConceptDraw PRO software are used the simple DFD flowchart symbols from the offered DFD libraries - Data Flow Diagram (DFD) library, Yourdon and Coad Notation library, and Gane-Sarson Notation library. The DFD objects are need to be connected each other by the arrows to depict the data flow from one step to another, that you can do in seconds in ConceptDraw PRO, as well as set desired design of your diagram.
