< programming > (OOD) A design method in which a system is modelled as a collection of cooperating objects and individual objects are treated as instances of a class within a class hierarchy . Four stages can be identified: identify the classes and objects, identify their semantics , identify their relationships and specify class and object interfaces and implementation. Object-oriented design is one of the stages of object-oriented programming .
