摘    要
随着国家信息化的发展，政府各部门间传统的人工公文交换方式已经不能满足政府建设的需要，迫切需要一种新的能够提高公文交换和办文效率的公文交换方式，在这种情况下，电子公文交换系统应运而生。电子公文交换系统建设的目的就是能够在不同的政府部门之间进行电子公文的传输和办文，各个部门通过统一的交换平台相互交换公文并进行办文，这种交换方式既能够支持各平级部门之间也能够支持上下级部门之间的公文交换和办文。
相对于传统C/S架构的胖客户端方式建立的电子公文交换系统，基于WEB的B/S架构的智能客户端方式建立的电子公文交换系统有明显的优势，用户无需在客户端安装专门的应用程序，只需要通过浏览器便能进行电子公文交换和办文。而对于整个系统的维护也只需在信息中心由专门人员执行，而无须对每一个用户进行维护。这种方式极大的减少了系统维护人员对系统维护和升级的麻烦，同时也使得用户从系统维护和升级中解脱出来。在这种公文交换系统中，各部门想要采用或放弃电子公文交换系统只需要系统管理人员进行相应的单位和用户添加和删除即可，无需其他特殊操作。通过这种电子公文交换系统，各个部门的电子公文可以进行统一的管理，同时对于电子办文也能够进行有效的跟踪。

The design and implement of e-document exchange system based on multi organizations
Abstract
 With the development of the national information, the traditional artificial exchange way of official documents between all departments can’t meet the further demand of our government, a new way (electronic official change system) which can improve the efficiency of transmission and implementation of official documents is highly needed. Aim of setting up the system is to make the convenient transmission and implementation of official documents between different sections, they can use it through the united exchange platform, and not only the same grade sections but also the higher and lower level can do official things fluently.
 Compared to the traditional electronic official document exchange system which is set up by the Fat Client with C/S architecture, there are many obvious advantages of the new system which is basic on Intelligent Client with B/S architecture of WEB. Users can handle all official things such as exchanging official documents through IE explorer, and needn’t to install specialized application procedures to the client. Specialized staffs will maintenance the whole system in the information centre instead of every user, it greatly reduced their troubles of system’s maintenance and upgrade, and meanwhile, users can be free from it. And if any department wants to start or close this electronic system, administers can just do corresponding actions. Documents of all sections can be managed through the electronic official document system, and we can urge and track the dealing of these documents effectively.
