Research on Query Processing Optimization of Heterogeneous Information Integration System
Zhai Xue-min · Microelectronics & Computer · 2008
Heterogeneous information integration system is a complex question,in order to reduce the data flow and the cost of oommunications and improving the efficiency of query,we analyse and investigate the query processing and query optimization in the heterogeneous information integration system.And on the basis of this,we investigate the means of optimizing the query.Using the more logical query policy and syntax is helpful for completing query task nicety and effi- cient,and advancing the system performance.
