<p>In the computer system of the present invention, the existence or non-existence of updates for master data for each partitioning key is managed as master data management information. If there is an update for the master data, the job is re-executed therefor, whereupon, at job re-execution time, the data is partitioned using only the partitioning key corresponding to the master data that has been updated, sub-jobs to be re-executed are localized in units by partitioning key, and the job is re-executed. (See FIG. 1)</p> |
