摘 要

随着网络的发展和高校教育改革的不断深入，大学规模的不断扩大，专业、班级、学生的数量急剧增加，有关学生选课的各种信息量也成倍的增加。以前那种人工操作实现学生选课管理的方法已经不符合现阶段的要求，因此迫切需求开发基于互联网的学生选课系统来提高教学管理工作的效率。选课系统成为学校教务管理系统中的一个必不可少的组成部分，可以实现学生查询自己和成绩信息、选课和退选，老师查询自己和所授课的信息、录入成绩和课程选修情况，管理员模块中包括学生、教师、课程和成绩信息管理等子模块:学生管理子模块实现对学生信息管理并且可以输入查询条件进行查询操作；老师管理子模块实现对教师信息的管理；课程管理子模块实现课程的管理，为课程分配代课老师并且查看某个课程的详细信息，并且此系统也是高校实现无纸化办公的一个必备工具。

本文阐述了基于ASP. NET的学生选课系统的工作原理和实现方法，分析阐述了学生选课工作的流程，并对系统功能目标和使用的数据库进行了系统的分析和设计，在此基础上实现了基于.NET的选课系统。利用此信息化的系统，实现了选课的动态管理，使得对信息的管理更加及时、高效和安全。

ABSTRACT

With the development of Internet and higher education reform unceasingly thorough, the university continues to expand the scale, professional, class, dramatically increasing of the number of students, the students of the amount of information also have increased. Previously the sort of manual operation to achieve the student management method can not meet the requirement of present stage, therefore urgently demand the development of Internet-based student elective system to improve the efficiency of education management work. Elective system become the school educational administration management system is an essential component, students can achieve the query itself and performance information, course selection and withdraw from the election, the teacher query and their teaching information, input results and elective courses, students, administrators module includes teachers, curriculum and performance information management module: student management module to achieve the student information management and can enter the query query operation; teacher management module to achieve the teacher information management; curriculum management module implementation of curriculum management, curriculum assign substitute teacher and view a program detail information, and the system is the realization of the paperless office an indispensable tool.

This paper based on the ASP . NET student elective system working principle and the realization method, analyzes the students' work flow, and system functions and database the system analysis and design, on the basis of the realization of course selecting system based on NET. Using this information system, realize the dynamic management of course selection, making the management of information more timely, efficient and safe.
