MANAGEMENT METHOD, MANAGEMENT PROGRAM AND MANAGEMENT APPARATUS OF DATABASE

摘要

A database management system includes a backup processing portion and a DB access processing portion. The backup processing portion operates to write data at a given time of a database stored in a storage unit out of the database after the given time as backup data. When an update request for data not written out as the backup data occurs in a data access request after the given time, the DB access processing portion writes the data at the given time out of the database as the backup data and updates the data written out of the database according to the update request. The backup processing portion and the DB access processing portion execute their processes in parallel.
