1、The paper focused on concurrency control mechanism of mobile transactions and proposed a concurrency control strategy based on dynamic timer.
2、Object versioning for optimistic concurrency control.
3、A new real-time optimistic concurrency control protocol is proposed, which USES importance of transactions.
4、Before updating the record, we used optimistic concurrency control with the set entity object method.
5、It also establishes the concurrency control strategy based on creator and event.
6、But while synchronization is primarily a concurrency control mechanism, transactions are primarily an exception-handling mechanism.
7、In a traditional database system, the transaction correctness is implemented through the concurrency control protocol and the recovery mechanism.
8、This paper studies the model of transaction execution and presents real-time validation concurrency control protocol(RTVCC)for RTADBSs.
9、In active real-time database systems, transaction concurrency control gets more difficult for integrating time constraint with active mechanism.
10、This concurrency control can greatly reduce timeout situations between readers and writers accessing the same data row.
11、Instead, we recommend the use of an optimistic locking strategy, delegating responsibility for concurrency control to appropriate application logic.
12、In order to further reduce the number of mobile real-time transaction restarts, we introduce the notion of similarity in concurrency control.
13、DB2 services such as optimization, indexing, concurrency control, and utilities are extended to support XML data along with the relational data.
14、Since Business Process Choreographer executes activities within transactions, concurrent access to Shared variables is governed by transactional isolation and concurrency control.
15、Mean a while the underlying principles of three typical kinds of concurrency control, those algorithm based on OPT (Operation Transpose) are studied deeply.
