The distributed database is the combination of computer network and database system. Due to the huge amount of data capacity across the global network, it is for granted that query processing and the optimization to be the key factor of query performance in distributed database. Query processing and optimization has been the key issue of database system research in the computer and communication development process, which can be seen through such a great deal of related literature and algorithms mining. Due to the physical distribution and redundancy of data, the difficulty and complexity presented in distributed database system and its query processing are both higher than that of centralized database system.
