摘要
以传统的事务并发算法为基础,分析移动数据库与分布式数据库的共性和差异性,探讨基于时间戳代理的并发控制改进模型。该模型经过从支持全局变量到支持不完整事务的演化过程,能够基本满足移动计算环境下各种应用场景的需求。
On the basis of traditional transaction concurrent algorithm, analyzes the similarity and differ ence between mobile database and distributed database. It discusses timestamp agent, the base of concurrency control improved model that has gone through the change process from supporting global variable to bug transaction and basic need of all kind of application context under mobile computing environment can be met.
