US Patent 7596573 System and method for automatic data mapping

A system and method for automatic data mapping of a source object to a target object. Field maps can be automatically determined from the source and target objects, database platform, ETL maps, user-defined and data conversion rules, default values, or other pre-defined parameters. Where a change occurs in the source or target data structure, the present invention ensures proper mapping between the source and target data structures occurs, thus reducing the burden of exception handling on the user and preventing oversight in correcting improper mapping. The present invention can also be used by a compiler to generate SQL steps during compile-time processes to design field maps that can be stored as an application class.
