| Abstract: | Data skew has great effects on the performance of parallel database systems. This paper presents record moving approach to resolve data skew, and makes decision between data-balancing strategy, load-balancing strategy, and re-partitioning. Simulated experiments are also made to compate our strategies. |

| Keywords: | Parallel database systems Data partitioning Data skew Reorganization |
