Explain the Object-oriented decomposition
Object-oriented decomposition targets at identifying individual sovereign objects that encapsulate both a state and certain behaviour. Each main components of the system is known as subsystem. Then communication between these objects leads to the required solutions. Decomposition of the system in function-data model (SAD) and the object oriented decomposition are given below. Although solutions help deal with complexity, you have reasons to believe that an object-oriented decomposition is favourable since, the object-oriented approach provides for a semantically richer framework which leads to decompositions which are more closely related to entities from real world. Moreover, the recognition of abstractions supports heaving solutions to be reused and object-oriented approach supports evolution of systems better, as those ideas that are more likely to change can be hidden within objects.
