DATABASE SYSTEM, METHOD FOR GENERATING REPLICA OF DATABASE, AND COMPUTER-READABLE RECORDING MEDIUM WITH RECORDED PROGRAM FOR REPLICA GENERATION OF DATABASE

摘要

PROBLEM TO BE SOLVED: To solve the problem that necessary data are not determined at the end of an updating process since various data are updated in a database and the updating process is performed in the order of the actual update of data at the time of the generation of a replica even when using methods and necessity of the data are different. SOLUTION: The priority of a replica generating process for some kind of data is stored, updated data of the database are preferentially extracted according to the priority, and replicas are updated with the extracted data.
