Example of DFD for Online Store (Data Flow Diagram)

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 Model

The DFD (Yourdon and Coad notation) example "Model of small traditional production enterprise" below was created using the ConceptDraw DIAGRAM diagramming and vector drawing software extended with the Data Flow Diagrams solution from the Software Development area of ConceptDraw Solution Park.

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

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.

Data Flow Diagram Symbols. DFD Library

Data Flow Diagrams show information transfers and process steps of a system. The general concept is an approach of a depicting how occurs input in a system, further processes and what runs out. The aim of DFD is in accomplishing of understanding between developers and users. Data flow diagrams are maintained with other methods of structured systems analysis.

Taxi Service Data Flow Diagram DFD Example

This sample shows the Data Flow Diagram of the Taxi Service and interactions between the Clients, Operators and Divers, as well as Orders and Reports databases.

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 DIAGRAM 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.

Data Flow Diagram Process

This example is created using ConceptDraw DIAGRAM enhanced with solution Data Flow Diagrams. It shows the process of account receivable.

DFD Flowchart Symbols

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.

UML Diagram for System

This sample shows the UML Class Diagram of delivery system. On this diagram you can see the classes that are connected with aggregation and composition associations indicated with the multiplicity. This sample can be used by delivery services, postal services.
