Query Optimization Strategies and Implementation Based on Distributed Database

摘要：

In this paper, on the basis of the research on the existing distributed query optimization, against the higher repetition rate, a new query processing program is presented, which completes the data dictionary, the overall model design, and then improves the query flow. Experiments shows that the strategies can improve the efficiency of the query, reduce the amount of middle data, and effectively reduce the total cost of network communication.
