| Abstract: | In this paper, the traditional parallel query processing algorithm is analysed, according to the features of the object oriented database and its query, based on the stage by stage executing strategy , the class based hybrid data placement strategy and the mark based data operation parallel executing algorithm, the semi join based parallel query processing algorithm is proposed, the correctness of the algorithm is proved, and the performance evaluation results of the algorithm are given. |
