Then , the development of dll is emphatically stated in the thesis . the dll encapsulates all the interface of opc data access and provides some api functions to people who develops opc server . the people can rapidly develop the server accorded with opc standard so as to shorten time of the server development 最后重点论述了动态链接库( dll )的开发，这个dll封装了opc数据存取规范定义的所有接口功能，并以一些api函数暴露给服务器开发工作人员，服务器开发人员可以使用dll快速开发符合opc标准的服务器，从而缩短了服务器应用的开发时间。
One the aspect of interface , thinking about the virtue of sql database on database technique , there are two parts : oa and mis in the designing . put the files of needing flow on the notes , and put a great deal of operation report forms which need to be statisticed on the sql data end , using interface ability with exterior database of lotus notes , through building odbc data resource and using programs to pick up the correlation data on sql end , and making the two system integrate together 接口方面，分析了lotusnotes平台结合sql数据库的特点，在设计系统时分为办公、业务两部分。把文件需要流转的工作或静态的数据放在notes端，而把大量的业务报表放到sql数据库端，利用lotusnotes提供的与外部数据库的接口功能，通过建立odbc数据源，在lotusnotes端编程实现提取sql数据库中的相关数据，使两个系统有机集成。
Secondly , the paper discusses the communication problem by making use of interface and gap , the system achieves purpose of realtime data sharing through experimentation , therefore , it performances function of realtime information supervision , operation performance calculation , operation performance loss analysis , improves manage level and safety supervision ability 其次,本文利用系统的接口功能,利用网闸技术,探讨了该系统与mis系统的通讯问题,通过试验,达到实时数据共享的目的,从而实现生产实时监控、单元机组性能分析、单元机组能损分析功能,提高全厂的业务管理水平和风险监控能力。
