Data flow diagram

A visual description of data flow in the system is called a data flow diagram(DFD). DFD is capable of explaining incoming data flow, outgoing data flow, and data storage. The data flow diagram describes how data flows through the system. DFD is developed using standardized notations and symbols. The data flow diagram represents the boundaries and scope of the whole system. Data flow graphs and bubble charts are the other names of DFD.
