Majority of the research in database management system focuses primarily on centralized database systems. However, with the demand for higher performance and higher availability, database systems have moved from centralized to distributed architectures. Concurrency control is an integral part of database systems. In this paper, the authors have proposed a new method of concurrency control on the basis of higher priority locking protocol. Assigning higher priority to the transactions requesting for read lock not only reduces the total execution of transactions but also reduces the waiting time for the transactions waiting in the queue.
