Rules for Stopping the Decomposition Process in DFD (1) when you have reduced each process to a single decision or calculation or to a single database operation; (2) when each data store represents data about a single entity; (3) when the system user does not care to see any more detail or when you and other analysts have documented sufficient detail to do subsequent systems development tasks; (4) when every data flow does not need to be split further to show that different data are handled in different ways; (5) when you believe that you have shown each business form or transaction, computer on-line display, and report as a single data flow; (6) when you believe there is a separate process for each choice on all lowest-level menu options for the system.
