<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.
