A data flow diagram (dfd) illustrates how data is processed by a system in terms of inputs and outputs.
14+ System Data Flow Diagram. Levels in dfd are numbered 0, 1, 2 or beyond. A dfd maker template can be useful to help guide a structured analysis of all informational inputs in a system so this can be visually pieced together. It shows logically what information is exchanged by our system processes and external interfaces or data stores, but it does not explicitly show when or in what sequence the information is.
