Data Flow Diagrams – Yourdon’s Technique

Data flow diagrams (DFD) show the flow of data or information from one place to another. DFDs describe the processes showing how these processes link together through data stores and how the processes relate to the users and the outside world.

They are used to record the processes analysed as a part of the design documentation. A DFD can be seen as a method of organizing data from its raw state. DFDs are the backbone of structured analysis that was developed in the early sixties by Yourdon.
