Study of Concurrency Control Techniques in Distributed DBMS

Manoj Gupta, Rakesh Kumar Arora ., Bhoopesh Singh Bhati

Abstract

Concurrency control focuses on maintaining consistency and integrity of database through synchronized access. The complexity relating to concurrency control in a distributed context is very high as compared to centralized framework due to maintaining consistency within the multiple fragments / copies of the database. This paper consolidates and discusses various lock based concurrency control techniques for Distributed DBMS. The paper also presents a comparative study of various two phase locking based concurrency control techniques.
