Data Flow Diagrams (DFD) visualize data flows in information systems.
They show: what kinds of data input to and output from the system; where the data come from and go to; where the data is stored.
DFDs are used for design and analysis of business and engineering information systems.
They are also used for data processing visualization.

The Data flow diagram (DFD) example "Payment for goods using UPS code scanner" shows data flow in process of payment for goods in the shop using the MaxiCode scanner.
"MaxiCode is a public domain, machine-readable symbol system originally created and used by United Parcel Service. Suitable for tracking and managing the shipment of packages, it resembles a barcode, but uses dots arranged in a hexagonal grid instead of bars. MaxiCode has been standardised under ISO/ IEC 16023.
A MaxiCode symbol (internally called "Bird's Eye", "Target", "dense code", or "UPS code") appears as a 1 inch square, with a bullseye in the middle, surrounded by a pattern of hexagonal dots. It can store about 93 characters of information, and up to 8 MaxiCode symbols can be chained together to convey more data. The centered symmetrical bullseye is useful in automatic symbol location regardless of orientation, and it allows MaxiCode symbols to be scanned even on a package traveling rapidly." [MaxiCode. Wikipedia]
This example of data flow diagram (Gane & Sarson notation) 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.
