摘要 对移动数据库系统的体系结构、移动终端的接入方式、移动计算环境下事务处理的真正需求等进行了详细的分析 .通过引入接入代理层的概念 ,屏蔽了计算终端的移动性 ;利用同步服务器屏蔽了后台中心数据库系统的异构性 ,并且能够解决多个移动终端在同步时的更新冲突 .从新的角度提出了一个完整的在移动计算环境下实现数据库事务管理的方案 ,并结合正在开发的一个移动数据库系统加以实现 ,实践证明这种方案是简单有效。 The architecture of mobile database system, the network connection mode of mobile terminals and the real requirement of transaction treatment in mobile computing environment are discussed in details. Through the introduction of the concept of connector layer, the mobility of computing terminal is shielded. By using synchronizing server, the heterogeneity of background center database is shielded, and the updating conflicts among mobile terminals while synchronizing are solved. A completed design of implementing transaction management in mobile computing environment is put forward in a new point of view, and implemented combining the development of our mobile database system project. The result suggests that this design is simple, effective and feasible.
