This paper presents an adaptive strategy called K-locking algorithm for concurrency control in databasesystem.The algorithm integrates an optimistic approach with the K-lock mechanism to control the degree oftransaction interference.It is shown that the K-locking strategy is adaptive to the changes in transactionparameters and outperforms both an optimistic approach and a pessimistic approach.
