学生选课管理系统

【摘要】

信息化的时代，把我们的生活装进计算机，装进数据库系统，让我们的生活井井有条。无论是生活、工作还是学习，我们都需要一个完善的系统帮助我们更好的记录。当然师生量庞大的学校对于数据库系统的需求更是迫切，所以本次课程设计就选择了学生选课管理系统。为了做出方便快捷的系统，我进行了需求分析，逻辑设计，物理设计，然后选用SQL Server 2005建立学生选课数据库，再用Visual Studio 2008设计了前台页面，就开发出了一个学生可以选课，教师可以录入并查询学生成绩，管理员可以管理学生信息、教师信息、课程信息等一列功能的学生选课系统。这个系统符合正常逻辑，操作简单，管理方便。 【 abstract 】

The information age, our life into the computer, put into the database system, let our life be arranged in good order. No matter in life, work and learning, we all need a perfect system to school for the on the choice of the student elective system. In order to make the system convenient, I conducted a needs analysis, logical design, physical design, and then choose SQL Server 2005The establishment of student course database, use Visual Studio 2008 to design the front page, it developed an elective students, teachers can record and query student achievement, the administrator can manage student information, teacher information, course information, the one one column function students select the lesson system. Normal logic, this system with simple operation, convenient management.
