Abstract
An execution system executes an update batch according to an update batch execution request from a terminal device and gives a batch execution command to each standby system. Each system stores the content of updated data in its update buffer; and subject to termination of the update batch by each system, the post-update data content is reflected in a database. While the above processing is performed, the execution system and the standby systems accept a reference request from the terminal device; and in a case of “batch not executed” or “batch in execution”, each system searches the database and then returns the pre-update data content to the terminal device; and in a case of “update content being reflected”, each system searches the database or the update buffer and then returns the post-update data content to the terminal device.
