This is a data flow diagram. A data flow diagram (DFD) shows the inputs and outputs of a system's processing of data. As its name suggests, it focuses on the movement of information, including the origin, destination, and method of storage of data. There are no loops, decision rules, or control flows in DFD. A flowchart can describe specific operations depending on the type of data. EdrawMax helps you create the DFD in a few clicks with its templates.
