METHOD FOR CONVERTING CENTRALIZED DATABASE INTO DISTRIBUTED DATABASE BY USING GENETIC ALGORITHM

摘要

PURPOSE: A method for converting a centralized database into a distributed database is provided to design schemas of a database according to formatted steps by using a genetic algorithm. CONSTITUTION: A method for converting a centralized database into a distributed database comprises steps of extracting schemas from a centralized database already constructed, synthesizing the extracted schemas, generating unit schemas for distributing data from the synthesized schemas by using genetic algorithm, arranging the unit schemas at physical sites, and normalizing the schemas, arranged at the physical sites, into a distributed database format. The genetic algorithm application method comprises steps of generating genetic chromosomes(S201), constructing an initial generation(S202), assessing the chromosomes of the initial generation(S203), performing a duplication operation on a dominance entity among the initial generation(S204), performing an interbreeding operation on the chromosomes of the dominance entity(S205) and performing a mutation operation(S206).
