| 摘 要： | 在分布式数据库系统中,由于数据的分布和冗余,使得分布式查询处理增加了许多新的内容和复杂性,通过分析现有分布式数据库查询处理技术,根据应用实际提出一种新的查询处理方法,该方法通过将常用查询结果存储在本地来减少查询时的数据传输量,从而缩短了响应时间.实验证明了该方法是有效的. |

| Abstract: | In distributed data base system,because of distribution and redundancy of data distributed to inquire increase a lot of new content and complexity.Based on the analysis of pioneer technology of distributed query processing,a new method for distributed query processing is proposed.The method can be used to reduce the quantity of data transfer through keeping parts of query results at local.Its validity is verified by an experiment. |
| Keywords: | distributed database query processing DD distributed query query optimization |
