A Data Flow Diagram (DFD) is useful for refining the scope boundary and defining what the system must do. It shows the flow of data between different entities and processes and helps to identify the inputs, outputs, and potential processing steps required to achieve the desired system functionality. DFD does not directly deal with database data modeling, system development responsibility, system features, or operations.
