摘要
移动事务处理是移动计算系统的一个基本功能,但是,移动计算系统固有的客户机的移动性、频繁的网络断接以及资源有限等特点限制了传统事务处理技术在移动系统的应用,因此,改进传统事务处理的方法使之适应移动计算的要求是提高移动事务效率的关键。介绍了移动事务的概念,分析了移动事务的特点以及移动事务处理的基本要求,提出了解决移动事务移动性、频繁断接性和数据一致性的关键技术。
Mobile transaction processing is a basic function of mobile computing system. However, due to the inherent characteristics such as mobility ofclient, frequent network disconnections and limited resources and so on in mobile computing system, the conventional transaction processing technologies are not support mobile system. So, improving the policies of conventional transaction processing for satisfying the requirements of mobile computing is a key problem to improve the efficiency of mobile transaction. The concept ofmobile transaction is introduced. The characteristics of mobile transaction and basic requirements of mobile transaction processing are examined. The key technologies used to solve mobility and frequent disconnections and data consistent of mobile transaction are advanced.
