Data Distributed Storage Management System and Distributed Storage Management Method

摘要

PURPOSE: A distributed data storage/management system is provided to safely store a data by storing the data to multiple data storage. CONSTITUTION: A distributed database management system divides a relation table of a data into fragments which are constituted with smaller relation table. A storage agent(50) distributes the fragments into a distributed data using a threshold secret diffusion method. The storage agent distributes and stores the distributed data to the data storages by the balanced incomplete block design.
