So while any data flow diagram maps out the flow of information for a process or system, the logical diagram provides the “what” and the physical provides the “how. The regular use of cash flow diagrams allows a faster approach to solve most TVM-related problems. Dataflow: data flow on context diagram either represents information produced within or outside the system which is used by outside world or by the system itself. A DFD is often used as a preliminary step to create an overview of the system, which can later be elaborated.
