A Distributed Query Optimization Research And Application
Li Xian · Microcomputer Information · 2010
Query optimization is a complex issue, but in a distributed system has an important role. In this paper, the analysis of the distributed query put forward approach based on global relationships table distributed query optimization, using a Wait_List to be updated to synchronize the global relational table to ensure that query results. The experimental results show that the method is effective in reducing the distributed query in the data communication, raising a distributed query speed.
