A Query Optimization Method Based on Quantum Genetic Algorithm in Distributed Heterogeneous Database

CHEN Ke-hua(Ning De Teacher College,Computer Department,Ningde 352100,china)  
To distributed heterogeneous database,query optimization is not only the very complicated question,but also the key factor about system capability.This paper combined with the advantages of genetic algorithm and quantum algorithm,brings forward an quantum genetic algorithm for algorithm and applied to solve the query optimization problem in distributed heterogeneous database.From the ex-periment result,its effect very good.
