... Converting raw data for input Summary Data flow design proceeds by initially analyzing the data flows and transformations within a software system. The first task is to draw the data flow diagram (bubble diagram), ... code for each new level. This transformation is straightforward and mechanical. We have now arrived at a program design capable of being readily translated into most c...
