摘要网上课程成绩分析系统是基于Web技术建立的，目的是帮助学生和老师进行成绩分析，包括成绩的录入与修改、课程的选择与录入以及对成绩的分析等。

该网上成绩分析系统是针对课程成绩方面开发的一款软件，它可以对学生成绩进行直观分析，进而使得学生对自身某些不足的科目进行有意识地关注与改善，也对教师开展的教学方法所取得的教学成果进行了一定的体现。它采用这种方式，可以减少错误，降低成本。87138

按软件工程的流程，本论文主要对网上课程成绩分析系统的需求分析和对系统的可行性进行分析，也阐述了系统的主要架构及开发模式，并对系统的详细设计，包括系统的设计思路、各功能模块和数据流图进行说明。另外，还介绍了运行环境和开发平台、系统各个功能模块的实现、数据库的设计以及具体功能及其对应界面的阐述。

最终本系统实现了学生、教师还有管理员三个模块的具体功能。在学生模块当中，实现了个人信息的查询和修改密码的功能，学生可以根据课程号查询相关课程并进行选课操作，也可查看已选的课程，学生能够查看自己的成绩，所获绩点并查看课程的排名，也能查看自己不及格的科目。教师模块实现了个人信息查看和修改密码功能，教师可以查看自己所教授的课程信息。在成绩管理方面，教师能够查看和修改所有学生成绩，后台自动对学生成绩进行分析，包括：平均分，不及格人数，高分人数，也绘制了详细的饼状图。管理员模块中，对登陆的管理员进行信息显示，可以添加新的管理员。可以添加新的课程，对于不需要的课程也可进行删除。

Abstract Online Courses achievement analysis system is based on Web technology to establish, with the aim to help students and teachers analyze the results, including the results of the entry and modification, the courses of selection and entry，as well as the course of the performance of the analysis etc。 

The online performance analysis system was developed into a software in order to analyze the course results，it can be visual analysis of student achievement。Thus making some of their own lack of student subjects were conscious attention and improvement。And it also can reflect the teaching achievement that was achieved by teachers’ teaching methods。In this way ,it is possible to reduce errors, and cost。And it also could lay a good foundation to realize further computer educational management system and school information system。 

According to the process of software engineering, this thesis mainly analyzes on the performance of the online course analysis system's demand analysis and the feasibility of the system and also describes the main structure of the system and development model, and describes the detailed design of the system, including system design idea, the system each function module and the system data flow diagram。In addition, it also introduces the operating environment and development platform, the system function of the specific implementation, the establishment of the system database, the specific functions and the corresponding interface。

Finally, the system realizes the concrete functions about student,teacher and administrators 。 In the student module, the student can the personal information and modify the password ,also can query related courses and elective operations according to the course number, can also view the selected courses。Besides students check their grades, grade point and view the course of ranking, also can view the subject that they do not pass。 In teacher module ,teacher can check their personal information and modify their password,also can view their subject that he teach。 In terms of performance management, teachers can view and modify all student achievement, automatic background on student achievement analysis, including: average scores, the number of passes, the number of high and plotted the with the pie chart。Administrator module, the landing of the administrator for information display, you can add a new administrator。 You can add a new course, to do not need the course can also be deleted。
