Distributed data bases : A summary of research

Abstract

The overall objective for distributed data bases is the sharing of data among several distinct but inter-connected computing facilities through an integrating mechanism. A review of the literature indicates that little progress has been made in this area due to the large number of technological problems involved. Some researchers have obtained analytical/theoretical results in the area of physical data allocation under the restrictive assumptions of static and known access patterns and independence between programs and data.The remaining unsolved technological and operational problems include measurement and evaluation techniques, maintenance of multiple image files, and security/privacy. In the next five to ten years significant benefits would accrue if data translation techniques, an integrated data base control system, and the integrated data base schema and physically distributed data issues were investigated.
