object-oriented design definition 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
