<p>PURPOSE:To improve the updating processing efficiency of an information system customer data base. CONSTITUTION:A transaction log stack part 2 distributes a transaction log record 1 generated by a calculating system to stores or store groups, and accumulates it temporarily in a schedule queue of a transaction log stack file 3. When a transaction log record 4 fetched through a schedule control part 5 is in a closed state on a customer data base 12, or there is a discrepancy in a sequence property of the transaction log record 4, a customer data base updating part 6 stores the subsequent transaction log record 4 of its customer in an error log file 10. Unless there is a discrepancy, the customer data base updating processing is continued. After all the transaction log records 4 of the transaction log stack file 3 are processed, a transaction log record 11 of the error log file 10 is read in order again and by an algorithm determined in advance, the transaction log record 11 is returned to the sequence of a correct transaction and the customer data base 12 is updated.</p> |
