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

Data flow diagrams (DFDs) reveal relationships among and between the various components in a program or system. DFDs are an important technique for modeling a system’s high-level detail by showing how input data is transformed to output results through a sequence of functional transformations.
Example of DFD for Online Store shows the Data Flow Diagram for online store and interactions between the Visitors, Customers and Sellers, as well as Website Information and User databases.

Data Flow Diagram

Data flow diagram (DFD) is the part of the SSADM method (Structured Systems Analysis and Design Methodology), intended for analysis and information systems projection. Data flow diagrams are intended for graphical representation of data flows in the information system and for analysis of data processing during the structural projection. Data flow diagram often used in connection with human process and can be displayed as workflow diagram. The critical Process Flow Diagram is another flowchart technique for designing data flow in connection with organizational processes. The critical Process flow diagram may use different range of symbols than a classic workflow diagram.

Data Flow Diagram Software

When studying a business process or system that involves the transfer of data, it is common to use a data flow diagram (DFD) to visualize how that data is processed. While initially used exclusively in regards to the flow of data through a computer system, DFDs are now employed as a business modelling tool, describing business events and interactions, or physical systems involving data storage and transfer.
ConceptDraw PRO is a powerful Data Flow Diagram Software thanks to the Data Flow Diagrams solution from the Software Development area of ConceptDraw Solution Park.
You can use the predesigned DFD vector objects that are grouped in 3 libraries of Data Flow Diagrams solution: Data Flow Diagrams Library; Gane-Sarson Notation Library; Yourdon and Coad Notation Library.
This DFD sample was created on the base of the figure illustrating "A Survey of Object-Oriented Methods" by Peter Biggs from University of Durham.

"Object-oriented analysis and design (OOAD) is a popular technical approach to analyzing, designing an application, system, or business by applying the object-oriented paradigm and visual modeling throughout the development life cycles to foster better stakeholder communication and product quality.
According to the popular guide Unified Process, OOAD in modern software engineering is best conducted in an iterative and incremental way. Iteration by iteration, the outputs of OOAD activities, analysis models for OOA and design models for OOD respectively, will be refined and evolve continuously driven by key factors like risks and business values." [Object-oriented analysis and design. Wikipedia]
The DFD example "Coad/ Yourdon's Object-Oriented Analysis model" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Data Flow Diagrams solution from the Software Development area of ConceptDraw Solution Park.

How to Create a Data Flow Diagram

Data flow diagramming is a highly effective technique for showing the flow of information through a system. Data flow diagrams reveal relationships among and between the various components in a program or system. DFD is an important technique for modeling a system’s high-level detail by showing how input data is transformed to output results through a sequence of functional transformations. The set of standard symbols is used to depict how these components interact in a system. ConceptDraw PRO allows you to draw a simple and clear Data Flow Diagram using special libraries.

Structured Systems Analysis and Design Method (SSADM) with ConceptDraw PRO

Structured Systems Analysis and Design Method SSADM is the method which is used at projecting and analysis of information systems. SSADM is based on the data flow diagrams. At the description of data flows out of the system and into the system DFD, which denote boundaries of the system, are used.
