The term \"Distributed\" in the concept of \"Distributed databases\" clearly signifies the nature of the database system that it is not at one place or location but residing at physically independent locations with some interconnection in the logical design. In this paper, the authors review the working of different concurrency control protocols in distributed databases. As the development and maturity of the popular centralized database system moves towards the distributed approach, the challenges and roles start becoming more complex and complicated. The discussion revolves around the variety of protocols, their working, their advantages and their disadvantages in a distributed environment. The paper is a comparative between the methods that are popular and accepted.
