  • (1) querying said relational database management system by means of a mapping system on said computer system on behalf of an application program associated with said application knowledge base as specified by a slot list and a class map of said mapping system for said arbitrary database, said class map having a slot whose values are slot maps, to return selected tuples;

    (2) transforming by means of said mapping system said selected tuples into slot values; and

    (3) supplying by means of said mapping system said slot values to slots of units of said application knowledge base.
