What is Object oriented Design ?

Object oriented design is an approach for software design. In this, system is decomposed into a set of objects that cooperate and coordinate with each other to implement the desired functionality. ISystem state is decentralized and each object is held responsible for maintaining its own state. That is, the responsibility of marinating the system state is distributed and this responsibility is delegated to individual objects. The communication and coordination among objects is achieved through message passing where one object requests the other object if it needs any services from that object.
