COM/COM+技术在中国实验动物信息网Web设计中的应用

Application of COM/COM+ to Web Design of China Laboratory Animal Information Net (CLAIN)

本文介绍在中国实验动物信息网络web网站应用新的技术COM COM +来改进和优化现有的设计。使用COM为核心的组件技术提供的开发平台 ,对现有的ASP设计代码进行优化设计 ,实现系统的可扩展性 ,使应用软件和系统软件能随着功能扩展、版本迁移和顺利升级 ,无须重编程序代码 ,更换底层支撑软件。本文以使用COM技术开发自定义数据访问组件以及该组件在ASP开发、VB、VC ++环境中应用为实例 ,阐述COM在中国实验动物信息网络建设中的作用和意义。

This paper introduces a new web technique-COM (an acronym for Component Object Model) for improving CLAIN web site and an instance of COM application to web design of CLAIN. COM is a way of building objects,that is independent of any programming language. COM as a core facilitates CLAIN development platform,which would obey the rule of CLAIN and extend functions with reusability. A data access component is designed in VC++. ASP.VB and VC application can call its function at the same time. And the role of COM in constructing CLAIN is discussed.
