What is a data flow diagram?

Data flow diagrams (or DFD) illustrate how data is processed by a system in terms of inputs and outputs. A DFD can document the flow of data within an existing system or a system that is in the process of being built or planned.

The foundation of any data flow diagram includes four components: terminators/external entities, processes, data stores, and data flows.

There are 2 types of notation used in a DFD: Yourdon & Coad or Gane & Sarson. They differ in the types of shapes used to describe a process and data store.
