Title:

DISTRIBUTED DATA BASE MANAGEMENT METHOD

Document Type and Number:

Japanese Patent JPH05173868

Kind Code:

A

Abstract:

PURPOSE: To realize a distributed data base management method which can smoothly execute data processing of required real-time processing without increasing memory volumes in individual node systems.

CONSTITUTION: Common DB 1 having a standardized system/structure and including data corresponding by all kinds of network is arranged so that all the node systems 2 to 8 can access it. Individual DB 2A to 8A including data needed only in the individual node system, data of which access frequency is high and data of which response is required to be in real time among all data are arranged in respective node systems 2 to 8. When an access requirement to objective data is generated, the individual DB is accessed first and if there is not the piece of data, common DB 1 is accessed to add objective data or a prescribed data block including it from common DB 1 to the individual DB.
