Distributed data bases

Abstract

The overall objective for distributed data bases is the shar-iTig of data among several distinct but inter-connected computing facilities through an integrating mechanism. A review ¢~f the liiterature indicates that little progress has been made in this area due to the large number of technological problems involved. ,Some researchers have obtained analytic'all ~heoreticai results in tiie area of physical data allocation unde: the restrictive ass[.mlptions of static and known access pa:.terns and independe'.~ce between programs and data.The remaining uns~',h.ed technological and operational l~r~,blems include mea~irement and evaluation techniqu.~s, maintenance of multipk image files, and security/privacy. In the next five to ten years significant benefits would accrue if data .translation techniqti~;s, an integrated data base control system, and rite integratcl, t dala base schema and physically distxibuted data issues were: investigated.
