英文摘要	An improved range data distribution method is proposed, which is suitable for both the homogeneous and heterogeneous database cluster with consideration of full use of different computing resources of nodes. In order to avoid the problem of load imbalance caused by the hot accessing, an online migrating algorithm is presented during the parallel processing. The experimental results show that the improved range partition method and the rebalancing strategy of online migrating algorithm not only significantly improve the throughput of database cluster but also keep the balanced state well. At the same time, the cluster system has achieved better scalability. ? Springer-Verlag Berlin Heidelberg 2009.; EI; 0
