Distributed Data Base Technology State-of-the-Art Review

摘要

This document provides theoretical information relating to the development of information systems where large data bases are utilized. The study considers the problems associated with the construction, implementation and maintenance of those data bases in a distributed processing environment. The data base management systems, data communications networking and the utilization of multi-processor configurations are also included in the investigation. Four specific problem areas of the update function under the distributed concept were studied and are reported upon. They are data integrity, logging and recovery, deadlock and security. (Author)
