在办公自动化蓬勃发展的背景下，本文结合中小型企业的需求分析，采用C/S设计模式，设计了内部行文管理系统。内部行文管理系统是采用PowerBuider9.配合SQL server 2000开发的一个数据库管理系统。本文逐一介绍开发本系统的步骤：系统分析、系统设计、系统实现、系统维护。在系统分析中先后用数据流图、系统的功能结构图分析了系统所需的各种数据。在系统的设计中，详细的展现了系统的各个功能模块，所需的数据库表及表字段，菜单的设计等。在系统的实现中，给出了实现表单中相应的功能控件的事件及代码，以及菜单实现的方法。文章的最后则给出了本系统的主要功能源代码。
本系统具有数据输入，数据存储，信息查询等功能，系统的人机对话界面友好。系统功能全面，用户操作方便是本设计的一个特色。

Abstract
In the context of development in the Office automation boom, using B / S mode, base on the needs analysis of Small or Medium Enterprises. In this article, this Administrative system of the document is designed for Small or Medium firms. It adopts a data base management system which is developed by PowerBuider9.0 and SQL server 200. This article recommends developing the step of this system one by one: analysis system, design system, realizing system, maintaining system. Successively with dataflow picture, and function structure chart various kinds of datum analyticl system take of system in network analysis. In the design of the system, detailed each function module which has represented the system, necessary database form and literary name section, and design of the menu, etc... In the realization of the system, provide and realize the incidents and codes of the corresponding function controlling part among forms. And the method is used to realize the menu. Provide the main function source code of this system at the end of the article. This system has data entry, the data are stored, file inquiry, such functions as the report form is typed, the interactive interface friendship of the system. The systematic function is overall, it is a characteristic that is originally designed that users are easy to operate.
Key word: Document, Face the Target, Document from Within, PowerBuider9.0, SQL Server 2000
