A Data Flow Diagram (DFD) is a graphical technique which allows effectively model and analyze the information processes and systems. The ability to fast and easy create the DFDs is made possible with Data Flow Diagrams solution from the Software Development area of ConceptDraw Solution Park. For designing the Data Flow Diagrams are used simple DFD flowchart symbols which are connected each other by arrows depicting the data flow from one step to another.
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.
UML Deployment diagram describes the hardware used in system implementations and the execution environments and artifacts deployed on the hardware.
ConceptDraw has 393 vector stencils in the 13 libraries that helps you to start using software for designing your own UML Diagrams. You can use the appropriate stencils of UML notation from UML Deployment library.
The vector stencils library UML Use Case contains specific symbols of the UML notation such as actors, actions, associations and relationships for the ConceptDraw DIAGRAM diagramming and vector drawing software. This library is contained in the Rapid UML solution from Software Development area of ConceptDraw Solution Park.
This sample shows the Use Case Diagram of parking lot control system. On this sample you can see use cases represented as ovals and three actors represented as figures of persons that employ these use cases. Associations between actors and use cases are shown as lines.
UML Diagram of Parking - This diagram can be used for understanding the process of working the car parking, at the projection and construction the parking by building companies and for automation the existing parkings.
