Abstract: A method, apparatus, and article of manufacture for cataloging datastore characteristics and defining and generating datastore persistent objects. A computerized system includes an external non-object-oriented datastore and a class definition tool that defines a specification for the external non-object-oriented datastore, defines a specification for a datastore persistent object class using the specification for the external non-object-oriented datastore, and defines a specification for an application program that interacts with the datastore persistent object class. The class definition tool stores the datastore specification, the datastore persistent object class specification, and the application program specification in a catalog.

Abstract: A method, apparatus, and article of manufacture for cataloging datastore persistent object class characteristics. A computerized system in accordance with the principles of the present invention includes an external non-object-oriented datastore and a class definition tool that defines a specification for the datastore, defines a specification for a datastore persistent object class using the specification for the datastore, and augments the datastore persistent object class specification to constrain use of the datastore by datastore persistent objects. The class definition tool stores the datastore specification and the datastore persistent object class specification in a catalog. The class definition tool further uses the datastore specification and the datastore persistent object class specification to generate datastore persistent object class and schema mapper class definition and method source code.
