This interface not only ensures the independence of HIS, but also realizes the openness of HIS. Thus, the Military No.l system is a secure and controllable system which is open to the 3rd party system.%使用Web Services技术实现LIS,PACS等业务子系统与HIS系统信息集成,消除信息孤岛.对HIS中常用的、需对外公开的功能和服务最小子集进行了总结和梳理.并按照"按需定制"的方式对接口进行扩展,以适应新接入的系统.该接口既保证HIS系统的独立性,又实现了HIS系统的开放性,使军卫一号HIS系统成为一个可与第三方系统互联互通,而且又是安全、可控的系统.
