The formal, structured analysis approach employs the data-flow diagram (DFD) to assist in the functional decomposition process. It conquers advanced structured analysis techniques, and those techniques are representative of present conventions. To summarize, DFD's are comprised of four components:

  • External interactors are represented by a rectangle.
  • Data stores are displayed by an open rectangle (2 or 3 sides).
  • Processes are represented by any rounded object (a circle, oval, or square with rounded corners). A DFD process may represent system function at one of various levels, atomic through aggregate.
  • Data flows are represented by arrows, with labels indicating their content.
