Study on Optimized Algorithm for Distributed Database Direct-join Query

YU Xiuxia~(1,2) ZHAO Jianping~2 (1.Network information Center,Changchun University,Changchun 1300222.Changchun University of Science and Technology,Changchun 130022))  
For distribute database query,join operation is the kind of the most common use with time-consuming and higher price and also it is the key confluence factor of the query efficiency.This paper presents an optimized query algorithm,which adopts direct-join using data partition and parallel processing.It can reduce the response time of query process.
