摘要: 在分布式数据处理及信息集成应用中,大量使用涉及信息源本地基表的连接运算的查询,其结果往往数据量非常大,而这样的查询可能会被多次重复地使用,因此,如何降低数据通信量对于提高系统性能至关重要。提出了一个基于查询定义的分片传输算法来降低数据传输量。

Abstract: The application of data distributed processing and information integration always relates to joining query based on basic table of data source.But the query is repeated and the scalar of traffic is very large.So it is important to reduce traffic,which would affect the efficiency of the whole system.The paper puts forward the data partition algorithm based on query definition in order to reduce transmission costs.
