ABSTRACT:
An online database system executes an update or reference process for a plurality of records without stopping the online system by registering the update or reference process for reservation. By registering an update or reference process for a plurality of records for reservation beforehand, the reserved access process is executed at the designated reservation access time. The reservation update process is executed by a preliminary process for registering the process for reservation and a reservation update posterior process which is executed at the time of first access to the record after the reservation update time and the reservation reference process is executed by a preliminary process for registering the process for reservation, a posterior process which is executed after the reservation reference time, and a reservation reference backup process which is executed when an update process for said record which is generated after the reservation reference time and before the posterior process is executed.
