Data Flow Diagram


A data flow diagram is a visual representation of a system’s data flow, specifically the systems for data processing and data transfer.

To construct a data flow diagram, one must identify the data coming into the system from outside sources and the data leaving the system, discover the relationships between incoming and outgoing data and determine the outcomes of those relationships. This information will make up the bulk of the data flow diagram.
