It is a graphical representation that is very easy to understand as it helps to visualize the content. Why DFD?ĭata-flow diagrams provide a graphical representation of the system that aims to be accessible toĬomputer specialist and non-specialist users alike. The end result of a well-developed DFD is a “big picture” that shows what is happening at each level. Provides an overall view of the complete system, as well as a more detailed decomposition and, where appropriate, a more detailed breakdown and description of individual activities to facilitate clarification and understanding.Īs a result, the scope and boundaries of the system are clearly indicated in the diagram. The DFD technique decomposes the high-level data flow diagram into a set of more detailed diagrams, providing an overall view of the complete system, as well as more detailed decomposition. DFD does not mention how data flows through the system. It can describe incoming data flows, outgoing data flows, and stored data. A data flow diagram is a graphical representation of the flow of data in an information system.
