(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.
