Abstract:
A new conversion database associated with information to be finally stored in a host information database is stored in a RAM along with a previous conversion database. Each processing unit refers to the new conversion database to identify data to be held in the host information database of the processing unit itself and refers to the previous conversion database to identify the processing unit which currently holds the data thus identified. The processing unit further relocates the data to be held in the processing unit itself from the processing unit thus identified.
