学生选课系统的设计与实现
【摘要】 在没有学生选课系统以前，传统的选课方法是在课堂上报名。这种方法虽然简单，但是需要消耗大量人力财力，并且容易发生数据丢失和统计错误。而选课系统即能实时地对大量选课数据进行检验和统计，输出选课结果，又避免了人工处理时容易产生的错误。因此，自动化的学生选课系统已经成为必需。
学生选课系统是高校教学管理系统的重要组成部分，本系统采用Browser/Server(B/S)结构，使用JSP网络编程技术，MySQL数据库，充分利用计算机网络功能，实现无纸化网上选课。本系统供三种用户使用，其中管理员可以对整个系统进行综合的管理；学生可以查询课程的基本信息，实现选课和成绩查询；教师可以查看选课学生的基本信息，输入成绩。
本文首先阐述课题研究的意义和目的，然后介绍使用的相关技术，接着对系统进行分析，最后讲述了系统的设计与实现，系统测试。
【关键词】 选课系统，JSP，B/S模式，MySQL数据库，自动化

A student elective system design and Application
[ Abstract ] in the absence of students elective system previously, the traditional elective method in class registration. Although this method is simple, but need to waste a lot of manpower and financial resources, and prone to data loss and statistical errors of the problem. But the course selection system is to timely for large classes of data check and statistics, output selection results, while avoiding the artificial processing is prone to error. Therefore, the automation of the student elective system has become the indispensable.
Students elective system is a system of university teaching management important component, the system adopts Browser / Server ( B / S ) structure, the use of JSP network programming technology, MySQL database, make full use of computer networks, to achieve paperless online course. This system for three kinds of users, the administrator can on the whole system to conduct a comprehensive management; the students can query the curriculum basic information, realize the course and achievement inquiry; teachers can show students the basic information, enter the results.
This paper describes the research meaning and purpose, and then describes the use of the relevant technology, and then carries on the analysis to the system, and finally describes the design and application of the system, system testing.
