Differentiate between the object oriented decomposition and the structured decomposition?
Process-oriented (structural) decomposition divides a complex process, function or task into easier subprocesses until they are easy enough to be dealt with. The solutions of these subfunctions then require be integrating and executing in certain sequential or parallel orders in order to obtain the solution to large complex system. On the other hand object-oriented decomposition targets at identifying individual autonomous objects which encapsulate both state and certain behaviour. Each main component of system is called subsystem. Then, communication between these objects leads to desired solutions. Object-oriented decompositions of the systems tend to be better able to cope with modification. Each subsystem has well-defined interfaces that communicate with rest of system.
