Query Optimization in the Object-Oriented Database Using Equi-Join

摘要

In this paper, we present an approach using equi-join that permits to enrich technique of query optimization existing in the object-oriented databases and the comparative analysis of query optimization for relational databases and object oriented database based on cost, cardinality and no of bytes. Our experimental study shows that the improvement in the quality of plans is significant only with decrease in cost. Seen the success of query optimization in the relational model, our approach inspires itself of these optimization techniques and enriched it so that they can support the new concepts introduced by the object oriented databases.
