Abstract

An integrated approach to query rewriting in an extensible database server supporting ADTs, objects, deductive capabilities and integrity constraints is described. The approach is extensible through a uniform high level rule language used by the database implementor to specify optimization techniques. This rule language is compiled to enrich the strategy component and the knowledge base of the rewriter. Rules can be added to specify various aspects of query rewriting, including operation permutation, recursive query processing, integrity constraint addition, predicate simplification and method call simplification
