无线医疗PDA系统中数据交换中间层的设计与实现

无线医疗PDA系统是面向医疗应用的个人数字助理系统,它通过PDA无线接入医院以太网来实现对原有医疗信息系统的扩充,具有移动灵活、携带方便的特性。但是在WindowsCE操作系统下进行的嵌入式编程缺少对直接访问网络数据库功能的支持,为了解决这个问题,文章在开发无线医疗PDA系统的实践基础上,提出了在无线医疗PDA系统中加入一个数据交换中间层的方法,顺利实现了无线PDA系统直接对网络数据库的访问。

Design and Implementation of Data Exchange Middle-layer in Medical Wireless PDA System

Medical Wireless PDA System characterized by mobility and facility is the extension of Medical Information System.However,there is one problem in programming with Windows CE OS.The problem is that embedded programming in Windows CE OS is lack of the ability of directly accessing database in network.To resolve the problem,the paper presents a method,which is to add a Data Exchange Middle-Layer in Medical Wireless PDA System,allowing Medical Wireless PDA System reaches the ability of directly accessing database in network.
