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 PRO 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. Read more

Data Flow Diagram (DFD)

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.

Example of DFD for Online Store (Data Flow Diagram) DFD Example

Data Flow Diagram (DFD) is a methodology of graphical structural analysis and information systems design, which describes the sources external in respect to the system, recipients of data, logical functions, data flows and data stores that are accessed. DFDs allow to identify relationships between various system's components and are effectively used in business analysis and information systems analysis. They are useful for system’s high-level details modeling, to show how the input data are transformed to output results via the sequence of functional transformations. For description of DFD diagrams are uses two notations — Yourdon and Gane-Sarson, which differ in syntax. Online Store DFD example illustrates the Data Flow Diagram for online store, the interactions between Customers, Visitors, Sellers, depicts User databases and the flows of Website Information. ConceptDraw PRO enhanced with Data Flow Diagrams solution lets you to draw clear and simple example of DFD for Online Store using special libraries of predesigned DFD symbols. Read more

Network diagrams with ConceptDraw PRO

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

Design Data Flow. DFD Library

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

How to Draw a Pyramid Diagram in ConceptDraw PRO

Pyramid diagram (triangle diagram) is used to represent data, which have hierarchy and basics. Due to the triangular form of diagram, each pyramid section has a different width. The width of the segment shows the level of its hierarchy. Typically, the top of the pyramid is the data that are more important than the base data. Pyramid scheme can be used to show proportional and hierarchical relationships between some logically related items, such as departments within an organization, or successive elements of any process. This type of diagram is often used in marketing to display hierarchical related data, but it can be used in a variety of situations. ConceptDraw PRO allows you to make a pyramid diagram, quickly and easily using special libraries. Read more
