Contribution

It presents a generic, customizable benchmark for object-oriented databases, focusing on clustering performance evaluation and demonstrating its application on a real system.

Findings

OCB can be tailored to different database schemas.

The benchmark effectively evaluates clustering policies.

Initial tests on DSTC clustering policy show promising results.

Abstract

We present in this paper a generic object-oriented benchmark (the Object Clustering Benchmark) that has been designed to evaluate the performances of clustering policies in object-oriented databases. OCB is generic because its sample database may be customized to fit the databases introduced by the main existing benchmarks (e.g., OO1). OCB's current form is clustering-oriented because of its clustering-oriented workload, but it can be easily adapted to other purposes. Lastly, OCB's code is compact and easily portable. OCB has been implemented in a real system (Texas, running on a Sun workstation), in order to test a specific clustering policy called DSTC. A few results concerning this test are presented.
