Concurrency Control entails the synchronization of accesses to the distributed database, such that the integrity of the database is maintained. Devising an efficient concurrency control technique is challenging. There is a need for improvised concurrency control technique to coordinate the simultaneous execution of transactions in a multi-processing database system. Traditionally, concurrency control techniques are locking, timestamp ordering and optimistic. These techniques have been evaluated by analytical modeling. In this undertaken work, the analytical modeling has been investigated and evaluated. The concurrency control in order to improve optimistic validation method with the traditional techniques, a new technique has been proposed.
