The traditional pessimistic lock-based concurrency control mechanism which focuses on the data's consistency and the transactions' concurrency cannot meet the demand that the in-time database systems make on the temporal consistency. This paper presents a new concurrency control method which is based on the locking, multi-version and single phase commit protocol concurrency control mechanisms, after the improvement of the concurrency control protocol for in-time transactions. Furthermore, the authors have adopted a method which is based on different concurrency control mechanisms according to the idiographic situation.
