1. A method for automatically mapping information of an object said information comprising the object attributes, relationships, and inheritances between an object-oriented application and a structured database, said method being carried out using a digital computing system comprising a processor, said method comprising the steps of:

  • executing instructions on said processor to load into temporary storage an object model, said object model comprising a plurality of semantic elements, said semantic elements being less complex than object class source code definitions, representing a plurality of object classes and a plurality of relationships between said plurality of object classes within said object-oriented application, each of said plurality of semantic elements comprising relationships between object classes, inheritances between object classes, and attributes of an object class comprising at least one object ID attribute;

    executing instructions on said processor to automatically generate code by parsing said object model to identify the object classes and their relationships for which said code is generated and automatically generating class definitions and methods, said code being suitable for conversion to an executable form that when executed automatically maps said information between said object-oriented application and said structured database; and

    executing instructions on said processor to output to persistent storage said code.
