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.

UML Flowchart Symbols

The UML diagram is a powerful tool which lets visually represent all system's components, the interactions between them and relationships with external user interface. The Rapid UML solution for ConceptDraw DIAGRAM software offers diversity of UML flowchart symbols for drawing all types of UML diagrams.

Data Flow Diagrams

Data Flow Diagram (DFD) is a special chart type which lets graphically illustrate the "flow" of data through an information system. So the Data Flow Diagrams can be successfully used for visualization of data processing or structured design, for creation an overview of the system, for business process modeling, for exploring the high-level design in terms of data flows and documenting the major data flows. Inclusion of powerful Data Flow Diagrams solution to the Software Development area of ConceptDraw Solution Park makes the ConceptDraw DIAGRAM a beneficial data flow diagramming software and supplies it with numerous collection of quick-start templates, professionaly designed samples, and extensive range of ready-for-use vector objects consisting the Data Flow Diagrams, Gane-Sarson Notation, and Yourdon and Coad Notation libraries. Use the ConceptDraw DIAGRAM application to design easy and quickly the Data Flow Diagrams including the data storages, data flows, external entities, functional transforms, control transforms and signals.

Program Evaluation and Review Technique (PERT) with ConceptDraw DIAGRAM

Program Evaluation and Review Technique (abbr. PERT) is a method developed by Ministry of Defense of the USA in 1958 for the project of creation the missile system Polaris. PERT diagram is one of the tools for project management that lets greatly simplify the planning and scheduling of large and complex projects. PERT diagram provides evaluation of project run-time and labor forces, it helps to analyze the time necessary for execution each of project tasks and the whole project, and to calculate the project critical path. PERT chart depicts the set of tasks connected each other in order of their execution and is constructed according to one of definite rules - AOA (activity on arrow) or AON (activity on node). It doesn't give you ready concrete decisions, but helps to find them. Design easy the PERT diagrams in ConceptDraw DIAGRAM software enhanced with Seven Management and Planning Tools solution from Management area of ConceptDraw Solution Park. You have a possibility to build the PERT chart of any type, but AON variant is easier for building and perception.

Campus Area Networks (CAN). Computer and Network Examples

Campus Area Network (CAN) is a computer network which provides wireless access to the Internet or LAN for the users located in two or more buildings on the limited geographical area, or in the open space surrounding these buildings. Campus Area Network is usually set in campus of a university or college, but the same kind of planning and design can be applied for other purposes, for enterprises, office buildings, military bases, industrial complexes, public places like supermarkets, entertainment centers, etc. Another form of temporary CAN can exist during some special events such as rallies, music festivals. The elementary Campus Area Network can also arise spontaneously, due to the distance of spread the radio signals from the access points that are not limited by buildings walls. It is also sensible to have additional access points for the larger and more complex CANs, located at specially places chosen for serving clients. Design easy diagrams and schemes for the Campus Area Networks with Computer Network Diagrams solution for ConceptDraw DIAGRAM.

Cloud Computing

The Cloud Computing is the use of the software and hardware that includes the great number of computers connected over the communication network such as the Internet. The Cloud name comes from the usage the cloud symbol on the system diagrams as the abstraction for the complex network infrastructure. This term is used as a marketing metaphor for the Internet. This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the Cloud Computing.
