What is a DFD?

A data flow diagram (DFD) represents the flow of information through a system. DFDs quickly became a popular way to visualize the major steps and data involved in software-system processes. They were used to show data flow in a software system, although they could in theory be applied to business process modeling. DFDs were useful to document the major data flows or to explore a new high-level design in terms of data flow.
