1. A system comprised of one or more computers for executing a digitally encoded database query received by the system, said query being expressed in a semantic query language, on the contents of a relational database with a corresponding relational database schema, said system comprising:

  • A module adapted to automatically translate the received database query into a second digitally encoded database query expressed in a relational query language by using a subset of the contents of a mapping data structure representing a mapping from the pre-existing relational database schema to a synthetic domain model that is a putative ontology automatically created from the relational schema, in order to create a translated relational query; and

    A module that is adapted to execute the translated query on the relational database, said execution module being operatively connected to the query translation module.
