    • A technology capable of preventing a problem which occurs when log writing of a preceding transaction fails while reducing waiting time of a subsequent transaction is provided. A database control method for releasing locking of data held by a transaction upon reception of a transaction completion instruction from an operation terminal or the like by a database is provided. The database includes an exclusive control module, a log output module, and a log buffer. The log output module stores a transaction completion log in the log buffer upon reception of the transaction completion instruction from the operation terminal. The exclusive control module releases locking held by the transaction upon reception of storage of the transaction completion log in the log buffer.
