We have proposed a new concurrency control algorithm for mobile XML databases with time-out based locking mechanism and addressing long-lived transactions [5]. In this paper, we present the implementation details along with improvements in the transaction manager. Using the proposed time-out based ...
In multi-user concurrent database systems, unexpected user interactions can compromise data integrity if not managed correctly. Locks and locking mechanisms, like the two-phased locking mechanism, are some of the measures available to help preserve data integrity. ...
