1 Answer

Answer :

Ans The most commonly used software design strategy involved decomposing the design into functional components with system state information held in a shared data area. The design strategies are: 1. Functional design The system is designed from a functional viewpoint, starting from with a high level view and progressively refining this into a more detailed design. The system state is centralised and shared between the functions operating on that state. 2. Object-oriented design: The system is viewed as a collection of objects rather than as functions. Object-oriented design is based on the idea of information hiding. In a object-oriented design, the system state is decentralized and each object manages is own state information
