摘　　要：数据同步技术是移动数据库的关键技术之一,也是移动系统进入应用阶段必须解决的难题。文章分析移动数据库的结构和特点,针对性地提出了一个基于移动Agent和Web服务的同步模型。模型针对实际运行环境克服了通信网络质量差和数据库选取受限制的不利因素。利用移动Agent技术解决了移动数据库同步过程中的网络不稳定难题。通过部署Web服务把同步逻辑和数据库分离开,并可实现灵活可靠的移动数据库同步。Data synchronization is the crucial part of mobile database technology,and it is also a problem must be solved for mobile database at the stage of application.This paper analyzes the structure and the features of the mobile database,a targeted synchronization model is proposed based on mobile Agent and Web service.For actual runtime environment,the model overcomes several disadvantages,such as poor quality of communication networks and restricted database selection.By use of mobile Agent technology,network instability can be solved in the process of mobile database synchronization.Synchronization logic and database are separated through the deployment of Web service.Furthermore,flexible and reliable mobile database synchronization can be achieved by use of this model.
