Q. Discuss the various strategies of design. Which design strategy is most popular and practical?

Ans The most commonly utilized 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 as of a functional viewpoint starting from with a high level view and progressively refining this into a more detailed design. The system state is centralised as well as shared between the functions operating on that state.

2. Object-oriented design: The system is observation as a collection of objects rather than as functions. Object-oriented design is on the basis of idea of information hiding. In a object-oriented design the system position is decentralized and each object manages its own state information.
