Example of DFD for Online Store (Data Flow Diagram)

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 DIAGRAM 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.

Contoh Flowchart

The Flowcharts are graphical representations of algorithms, processes or step-by-step solutions problems. There are many different types of Flowcharts, among them Process Flowchart, Cross Functional Flowchart, Data Flow Diagram, IDEF Flowchart, Workflow Diagram, Contoh Flowchart and many others. They have especial value when you need represent a complex process, depict in details the process of solution problems, efficiently plan and set the tasks priorities. The Flowcharts must to be constructed brief, clear and logical, simplifying the process or procedure, and making easier the comprehension and perception of information. The ConceptDraw DIAGRAM software makes the process of creating the flowcharts of any types well organized and clear for developers and customers also, including the Contoh Flowchart. It is possible due to the Flowcharts solution from ConceptDraw Solution Park, its predesigned vector objects, templates, and a lot of professional-looking practical samples and examples which can be quick and easy modified, printed, or published on web.
