摘要这个课题是学生在线选课管理系统，在过去，学校在对学生选课时，可能需要使用一些人工方式去管理文件档案。而使用了这个学生在线选课系统可以很方便使学生选课，对学生选课更高效管理。72876

在学生在线选课系统，框架使用了j2ee框架对其规范，这样可以让选课系统开发速度更快，以及便于系统维护。

学生在线选课系统论文论述系统需求分析、系统设计、系统功能实现等方面，这些可以给之后编写工作一个指导方向。

在对选课系统设计，编写时集成了很多相关知识，包括对选课系统编写时需先对系统需求分析、系统模块设计、系统分层设计等，在对系统编写功能模块时，需要了解这些系统模块都应该实现哪些功能。然后在编写时，可以有个更好的编写方向。

而且针对很多选课系统会频繁出现多选、错选等情况，这个选课系统特实现了系统推荐选课功能，帮助学生选择合适自己的课程。这样，就更加完善了选课系统，使选课系统不单单是一个选课工具，更可以在课程选择、学生学习方向方面，给学生更多指导意见。

Students online course management system design and implementation

Abstract This subject is the student online course management system, in the past, schools in the course of students,some may need to use artificial means to manage documents; And use the students online course selection system can easily make the students' course selection,elective for students more efficient management。

In the student online course selection system is used,including。 In course selection system framework USES j2ee framework for the specification,so that we can make course selection system development is faster and convenient for system maintenance。

Students online course selection system paper discusses system demand analysis, system design, system functions,etc。these can be a guidance to write after work。

In course system design,when learning a lot of knowledge,including the first course is required for a system to write on the system demand analysis,system module design, system hierarchical design,etc。in written to the system function module,need to understand these systems which function module should be implemented。 Then,when writing,you can have a better writing direction。

And for a lot of elective system will appear frequently multiple-choice,wrong choice, and so on and so forth,the elective system,to realize the recommended course selection function system,help students to choose their own courses。 Such,are more perfect elective system,make the course selection system is not only a course selection tool, more can choose the course,students learning direction, to give students more guidance。
