The Architectural Design Process

The Data flow oriented design is an architectural design technique which allows a convenient transition from the analysis model to a design description of program structure. Transition from information flow represented as a data flow diagram to structure is accomplished as part of a 5 step procedure.

1.    The kind of information flow is develop

2.    Flow boundaries are indicated

3.    The Data Flow Design is mapped into program structure

4.    Control hierarchy is defined through factoring

5.  The resultant structure is refined using design heuristics and measures the information flow kind is the driver for the mapping approach needs in step 3.  In the following sections we examine 2 flow kinds.
