A technique is provided, which increases a speed of processing of applying a transaction log to update a database. A computer which updates the computer's own database in use of a transaction log: acquires the transaction log; processes records in the acquired transaction log by sequentially referring to the records in the acquired transaction log from the first record, and with respect to a record related to an update instruction for updating data included in the database from among records included in the transaction log, executes the update instruction represented by the record when an object of the update instruction is read onto a memory of the computer and puts execution of the update instruction represented by the record on standby when an object of the update instruction is not read onto the memory of the computer; and executes the update instruction put on standby with respect to the object either until the object of the update instruction put on standby is read onto the memory and becomes a processing object, or when the update instruction put on standby has been read onto the memory and become a processing object. |
