Efficient concurrency control mechanism for distributed databases

Distributed database is not a new term in the current world. A distributed database is a set of several databases that are correlated to each other in a logical fashion over the network. Data is distributed as well as replicated at various locations in order to increase the availability. During recent years, data distribution has been evaluated as an important issue for databases. Since the data is distributed, it becomes necessary that all the copies be synchronized at the time of any data update, thus leaving all the copies with consistent data. This research paper will present a consistent concurrency algorithm which presents a solution to consistency problem of distributed databases.
