摘要
随着移动计算技术的发展，移动数据库逐步走向应用，在嵌入式操作系统中移动数据库更显示出其优越性。移动环境中所具有移动性、频繁断接收、低带宽、电池电量有限性等特性，决定了移动数据库中计算环境不同于分布式数据库，给移动数据库研究提出了许多新的要求。该文从分析移动数据库特点、体系结构；介绍移动数据库系统中一些关键性技术；Agent技术及移动Agent在移动数据库中的应用。
With the development of mobile computing technology, Mobile Database.is moving towards the application gradually,and displaying its superiority in Embedded Operating System.There are so many characteristics in Mobile Environment, such as mobility,frequent breaking receiver,low bandwidth,limited battery power and so on,which determined there must be some differences between Computing Environment of Mobile Database and Distributed Database and put forward a number of new requirements to the Mobile Database. This article introduces the Development Status of embedded Mobile Database,analyses characteristics of Mobile Database and its architecture and introduces the technology of Agent and the application of Mobile Agent in Mobile Database.
