J. Darmont, B. Petit, M. Schneider, "OCB: A Generic Benchmark to Evaluate the Performances of Object-Oriented Database Systems", 6th International Conference on Extending Database Technology (EDBT 98), Valencia, Spain, March 1998; Lecture Notes in Computer Science, Vol. 1377, Springer, Heidelberg, Germany, 326-340.


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.
