A New Query Optimal Method in Distributed Database System
Min Liu · Journal of Xuchang University · 2008
Distributed query process is difficult and complicated because of the physical distribution and redundancy of data.This article introduces the objective and some optimized query methods,and presents a new query algorithm: distributed inquiry process on the basis of two level-indexing,which can gain the best query path through the global indexing and local indexing and reduces wasted bandwidth in querying of distributed database system.
