Adding Inferencing to a Relational Database Management System

- Summary

Abstract

The LogiQuel System is a deductive DBMS which supports the management of clauses expressed in LogiQuel, a language with the expressive power of extended Datalog with negation. The inference mechanism used to evaluate LogiQuel queries is both sound and complete under the tight-tree semantics. The system is implemented on top of a commercial relational DBMS. After a brief overview of LogiQuel we show how a LogiQuel statement is translated into SQL for subsequent evaluation by the DBMS.
