Abstract  This paper takes the example of elementary CAT( computer-aided tolerancing) system to discuss the essential connotation that undertakes the demand analysis of object-oriented in the process of establishing systematic entirety structure. It explains the general steps of demand analysis the hierarchy of the objects and the class of the objects to classify the objects of each layer.

Key words： CAT      demand analysis      objected-oriented      functional layer      operation layer      class
