| 摘 要： | 设计了一个移动事务管理系统用来满足移动计算的诸多特征。客户端缓存部分数据，允许网络在断连时继续操作。在客户端，事务被定义为移动事务“程序”并被用来同步，可以定义详细的操作语义以及替代操作，还可以定义冲突解决方案。系统还提供了通知机制来通知移动用户移动事务的最终执行结果。

| Abstract: | Describe a transaction management system designed to face the inherent characteristics of mobile environments. Mobile clients cache subsets of the database state and allow disconnected users to perform transactions independently. Transactions are specified as mobile transactional programs that are propagated and executed in the server, thus allowing the validation of transactions based on application-specific semantics. Moreover, support for active user notification is provided in the system. |
