移动数据库在防汛掌上通系统上的应用

Application of Mobile Database in Flood Prevention System on PDA

论文针对防汛领域的实际需求,设计并实现一个基于嵌入式移动数据库的掌上防汛信息管理系统。系统的核心内容是基于SQL Server 2000企业数据库管理系统和SQL Server CE嵌入式移动数据库系统,利用各种编程技术(包括嵌入式系统开发技术、移动数据库技术、移动通信技术、网络编程技术、MXL技术),实现一个推动式信息服务的中间件,实现了SQL Server CE移动数据库的推动式数据服务方式,即实现移动数据库的数据广播技术,扩展了SQL Server CE的功能,满足了防汛领域的实际需求。

In order to satisfy the unique demand in flood prevention, this paper designs an implement a flood prevention information management system on PDA based on embedded mobile database. The most important part of this system is designing and implementing a middle-level software component based on SQL Server 2000 and SQL Server CE embedded mobile DBMS, using many kinds of programming technique （including embedded system programming, mobile database technology, mobile communication technology, and so on ）.This component realizes the Push-Style information service based on SQL Server CE, expanding the function of this embedded mobile database management system.
