METHODS OF QUERY OPTIMIZATION OF DISTRIBUTED HETEROGENEOUS DATABASE BASED ON GENETIC ALGORITHM

Lu Jinshi Li Hongxing La Xiao (Dept. of Inf.Eng. , Dalian Inst. of Light Ind. , Dalian 116034) (Xinjiang Institute of Physics, CAS, Wulumuqi 830011)  
Query optimization is very important to distributed heterogeneous database. In this paper,a genetic algorithm based on porition value tree sturcture encoding is used at problem of query optimization.Its effect is very good.
