SOME ASPECTS OF CONCURRENCY CONTROL IN DISTRIBUTED DATABASES

Abstract

Distributed databases allow the design of systems which present different features as compared to the traditional, centralized systems. It is therefore useful to look at the typical features of traditional databases and to compare them with the corresponding features of distributed databases. The features which characterize the traditional database approach are centralized control, data independence, reduction of redundancy, complex physical structures for efficient access, integrity , recovery, concurrency control, privacy and security.
