A Transformation-Based Approach to View Updating in Stratifiable Deductive Databases
Abstract In this paper we present a new rule-based approach for consistency preserving view updating in deductive databases. Based on rule transformations performed during schema design, fixpoint evaluations of these rules at run time compute consistent realizations of view update requests. Alternative realizations are expressed using disjunctive Datalog internally. The approach extends and integrates standard techniques for efficient query answering and integrity checking (based on transformation techniques and fixpoint computation, too). Views may be stratifiably recursive. The set-orientedness of the approach makes it potentially useful in the context of (commercial) SQL systems, too.
