Abstract :
Declustering schemes enable parallel data retrieval by placing data blocks across multiple disk devices. Various declustering schemes have been proposed for multidimensional data to reduce the response time of range queries. However, efficient schemes, which must be easy to compute and provide good performance, are only known for a restricted number of disks and dimensions. In this paper, we propose a novel technique to construct efficient multidimensional declustering schemes, for any number of disks and dimensions. Simulation results show that the new schemes outperform the best previously-known non-exhaustive search-based multidimensional declustering schemes
