  • A data flow diagram (DFD) is a visual representation of how data moves between processes and data stores inside or outside of a system as well as between external entities.
  • One of the deliverables for process modeling is context DFD.As seen on the DFD flow chart in Figure 5, a data flow diagram (DFD) is a graphical depiction of the "flow" of data through an information system, simulating various process elements.
  • Information traveling through processes and data stores to reach the system is known as data flow.The DFD can show you the direction of the data flow with arrows and brief labels.
