摘要
在移动数据库系统中,移动计算的特点决定了传统事务处理模式不再适应.采用乐观执行与两阶段提交相结合的方法,对移动事务处理方法进行了新的研究.为支持计算平台的断接性、长事务特征,提高断接事务的全局提交率,提出了一种支持断接操作的移动事务处理模型.模型在模拟平台上性能良好,对移动环境具有更好的适用性.
In MDBMS, the features of mobile computing determine that traditional transaction schemas are no longer applicable. This paper adopted the combination of optimistic executing and two - phase commit protocol to study the new method. In order to support the disconnection and long - lived transaction of clients, and to improve the global commit rate of disconnecting transaction, we proposed a new mobile transaction model which supports disconnecting operation. The performance is fine on the stimulant platform, and have better applicability to mobile environment.
