A DATA PROCESSING SYSTEM AND METHOD

摘要

A data processing system (1) has a processor (2) which has an initialisation function for setting up a framework (50) of product or service object oriented classes and sub­classes. Each sub-class (31-34) is for a component of the service with a logical grouping of rules. A run-time function generates a particular instance of the service by instantiating a contract class framework (53) which is derived from the service class framework (50). The contract objects may be modified within control limits imposed by rules of an alteration class (37) of the service class framework. A document describing the service in general terms may be generated from the service classes.
