摘要

 学生选课是一个学校教学管理中不可缺少的部分，但一直以来人们使用传统人工的方式管理文件档案。随着信息化建设的不断推进，现在大多数高校都已这现网上选课。
 本范文主要包括学生选课系统方案分析与系统开发，系统开发主要包括后台数据库的建立和维护以及前端应用程序的开发两个方面。对于前者要求建立起数据一致性和完整性强、数据安全性好的库。而对于后者则要求应用程序功能完备,易使用等特点。
 经过分析,笔者使用 MICROSOFT公司的SQL 2000、ASP (active server pages)作为开发工具, 用Microsoft Windows XP Professional 版本2002 Service Pack 2 简体中文版，Microsoft Offices ACCESS 2003 中文版，Internet Information Services (IIS6) Manager，Intel(R) PIIII CPU 3.0GHz Double CPU  512MB Rom 160GBHardDisk作为开发平台。
 在开发过程中，利用其提供的各种面向对象的开发工具,首先在短时间内建立系统应用原型,然后,对初始原型系统进行需求迭代,不断修正和改进,直到形成用户满意的可行系统。
 本系统可以方便老师、学生更方便的选课。实现全校学生选课在线查询。还可以对新来的学生信息进行信息录入。由于学生上课情况复杂，可以实现信息修改，及时调整学生的基本情况。

ABSTRACT
 
 It is an essential part of the management in school teaching that students choice the courses by themselves. But people use the traditional manual in the management of paper files all along. As the information construction progress continuously, the majority of colleges have been practicing to choice the courses online.
 Even though, incalculable economic loss are caused because many servers are attacked without effective detecting and defending. Many deficiency in technology are based on this passive defending system, then the active defending system come out of the surface and the representative is Network Inbreak Detecting System.
 The Ultimate function of this system is detecting and analysing the net behavior in real time and react to the result of the behavior. By this way, illegal attack can be pre-detected and loss can be avoided. The emphasis of this system is the property of active, not passive. The active property is also the reason while this system is so highly regarded!
 This thesis talked about the concept, origin, definition and sort of the Network Inbreak Detecting System. Also common Network Inbreak Detecting System work principle are mentioned. It analyses this system in modular layer, and the stress point is focused on data-package capture, the design and realization of analyse and store modular for network protocol.
