Optimization of Object-Oriented Queries: Problems and Approaches

  • Conference paper
Advances in Object-Oriented Database Systems

Part of the book series: NATO ASI Series ((NATO ASI F,volume 130))

Abstract

An object-oriented data model can support features such as abstract data types, methods, encapsulation, subtyping (or inheritance), complex structures, and object identity. The processing of queries in such a model must incorporate support for these features. Query optimization will require new techniques for supporting the object-oriented features. Although some of the problems that must be solved by an object-oriented query optimizer are similar to problems solved by relational and extensible optimizers, there are also many problems that are unique to the object-oriented data model.

In this paper we explore some of the problems that are encountered when trying to optimize queries in an object-oriented database management system. We present each problem in the context of the object-oriented modelling constructs generating the problem. We also survey current approaches to solving some of these problems.
