1              摘      要

步入21世纪,计算机在管理信息系统（Management Information Systems,MIS）中应用的普及,利用计算机实现管理信息系统有助于企业或其他用人单位方便实现数据处理、预测功能、计划功能、控制功能和辅助决策功能。MIS是现代用人单位日常工作中必不可缺的一部分,是适应现代管理制度的要求,推动用人单位信息管理走向科学化、规范化的必要条件。

在这篇论文中简单介绍了管理信息系统的背景及主要功能。并且以“成人教育学院学生信息管理系统”为例开发了一个简单的MIS系统。由于系统是基于面向对象的开发平台,所以在程序编写过程中多次采用了代码重构技术。后台数据库采用Microsoft Access2003。

本系统使用Java开发, Java程序设计语言是一种优秀的程序设计语言,具有简单、体系结构中立、高性能、可移植性等特点。集成开发环境选用了Borland JBuilder 2005 Enterprise。JBuilder是目前最好的Java开发平台,可用于开发大型系统工程。使用Borland JBuilder进行系统开发,可以方便的生成UML图,进行代码重构,或编写程序文档。

关键词：管理信息系统,面向对象技术,Java

With the high speedy development of electronic computer science, and the calculator is in the Management Information Systems, and make use of the calculator to realize the business enterprise personal management be imperative under the situation. The human resource already and gradually becomes the most important resources of the business enterprises. Management Information Systems that manage that importance, manage for human resource the market foreground to provide the amplitude.。。。。。。。。。。。。。。。。。
