Abstract

An object-oriented data processing system performs a desired processing based upon an object model including a plurality of objects each formed of data and methods. The data processing system includes an external definition that identifies the object and including an identifier for identifying the object, an internal definition for carrying out a procedure of the object and including an identifier corresponding to the identifier in the external definition, a model classification function for classifying the object model, based upon the external definition, into a static model that indicates a relationship between classes, and a dynamic model that indicates the time sequential relationship between instances forming the classes as a session, a causality restriction function that imposes a causality existing between the static model and the dynamic model, to the static model, a class generation function for creating the classes by combining existing and/or newly created methods; and an instance generation function for creating the instances in correspondence to each of the classes, wherein the class includes a composite class formed of a plurality of classes.
