| 摘 要： | The concurrency control problem in database systems has been examined by many people and several concurrency control algorithms have been proposed. The most popular algorithms are two-phase locking and timestamp ordering. Due to its inefficiency in some situations, we propose the optimized method which is combined of timestamp ordering and optimistic method. With this method, the efficiency can be improved in those systems where the conflicts between transactions rarely happen.
