General Rules for Creating Data Flow Diagram 1. Keep it simple; 5-7 processes is a good guide; no more than 7 - 9 processes in each DFD. If a process involves complex sub-process, start a new diagram and connect the 2 diagrams with hyperlink. Number the process. Showing the sequence is useful in identifying the processes when discussing with users.
Label the process properly and concisely to increase readability. Data stores should not be connected to an external entity because it would mean that you're giving an external entity direct access to your data files. Data flows should not exist between 2 external entities without going through a process. Loops are not allowed. A process is not an analog of a decision in a systems or programming flowchart.
Hence, a dataflow should not be a control signal. Control signals are modeled separately as control flows.
