需求分析

本系统主要功能：

1. 学生信息管理：对在校学生信息进行添加、删除、修改、查询等操作。
2. 学生成绩管理：对已经录入的学生信息进行添加、修改学习成绩，并可以通过关键字进行模糊查询。
3. 授课信息管理：支持对授课教师、课程编号及授课老师所授课的年级进行添加和修改操作。
4. 课程管理：可显示每个班级每学期的课程表，并可以对已经开设的课程进行添加、删除和修改。
5. 用户管理：用于管理系统用户，可进行账号增加、账号删除、权限修改等操作，方便对不同账号进行管理，避免系统权限混乱。

业务流程分析

本系统整体主要围绕学生、教师、课程、管理员用户登实体类展开，实现系统用户的身份权限判断，用户操作授权等等。系统整体用户角色操作流程如下：
