4、来设计本系统，在数据连接采用了数据源(ODBC)作为连接。本系统的基本功能为：学生选课管理、成绩的录入、成绩的查询、成绩考核、成绩排名和奖学金管理、学分管理、操作人员权限管理、成绩统计等。学生选课管理主要满足现代学生业余爱好，来选择自己的业余科目。成绩的录入用来实现对学生成绩的输入。如果想查询某人的成绩,可以根据成绩查询功能来查询他的成绩,查询可以按姓名和学号查询。成绩考核是用来考察这一学期来，学生的成绩情况。成绩排名是用来实现全部学生成绩的排名。选课管理主要是满足学生业余的爱好，来选择自己喜欢的选修课程。奖学金管理，表扬优秀学生而设立的，在单及格的基础上总分要达到一定的要求。学分管理是根据学
5、生选修课目的多少,来确定学生已经获得了多少个学分.成绩统计用来统计，各科分数在一定范围内学生的人员及信息。操作人员权限是为了防止非法用户进行非法的操作设计的。本系统还有许多其它的功能，这里不一一列举出来了。本次设计是理论与实践的一次有机结合，是一次尝试性的开发过程，同时也是增强自己实际动手能力的一次机会。在开发过程中，存在着许多的不足和问题，不过我相信在今后的工作和学习中将不断学习，力争做到最优的结果。关键字：成绩管理系统、java、关系型数据库、软件工程AbstractWith the economic globalization, the science and development h
