Areas of Application

Each and every software design techniques has weakness and strengths.A very important selection factor for design techniques is the breadth of applications to that it can be applied. The Data flow oriented design is amenable to a wide range of application field.In fact because all software can be represented through a data flow diagram a design technique which makes use of the diagram could theoretically be applied in every software development effort.  The data flow- oriented approach to design is particularly useful when data is processed systematically and no formal hierarchical data structure exists. Example for, numerical analysis procedures, process control; microprocessor control application complex, and several other engineering, scientific software applications fall into these types. The Data flow oriented design methods are also applicable   in data processing applications and can be effectual applied even when hierarchical data structures do exist.

There are cases, moreover, that a consideration of data flow is at  best a side issue. In like applications example for database systems, object oriented interfaces, expert systems, other design methods may be more appropriate
