Query Processing and Optimization in Heterogeneous Information Integration

摘要：

Query processing is one of the key techniques in HIIS(Heterogeneous Information Integration System), and query decomposition, scheduling and optimization are the central problems for query processing. This paper firstly defines the basic concepts of query processing and gives the architecture for it in HIIS, and secondly puts forward XML Integration Data Mode(XIDM) and query processing algorithm, and gives optimized algorithm of query processing, and finally build Panorama Web One to implement Heterogeneous Information Integration.
