摘要：The invention proposes a method of defining and generating cooperatingobject structures for accessing Business Applications (BAs) which were not built upon theprinciples of object orientation (OO) in an OO manner. One step of the method istargeted at the definition of true Business Object (BO) classes with a unique meaning asentities or concepts in terms of the underlying business as supported by the BA. As theBAs process the business relevant data, their spectrum of the input and outputparameters serve to define the BO Attributes (BOAs) of the individual BO classes. Afurther step of the method is the encapsulation of the individual BAs within TransactionalObject (TO) classes for controlling and executing the BAs. TO instances are able toautonomously extract BOA values from the BO instances to assemble the input
parameters for BA execution. The TO instances are also endowed to process the outputparameters as returned by the BA to materialize BOs, i.e. to extend existing BOs with newBOAs or to instantiate new BO instances. Interacting with the BOs may transparently
result in executing BAs with the TOs thus the BOs support an OO-access of the BAs. TheBAs may even be executed on a remote data processing system as TOs are able to drivecommunication protocols.
