object-oriented design
     
         (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}.
