  • 系统开发背景

随着我国教育产业的飞速发展,社会对教育水平和教学管理软硬件的要求日益提高,尤其是对一个学校能够具有一套完善的教学管理软件提出了更多的要求。为了适应这种形式,教育系统尤其是大学不仅首先要有坚实的硬件基础,还要有一套完善的教学管理软件管理系统。而要实现这一功能,就要要求学校管理者配备一套高效的教育管理网络系统,以便在学校里实施良好的一套完善的管理且以最快的速度响应教师和学生的需求,及时为他们提供服务,为他们提供一个高效、便捷的环境。学生信息管理系统是校园网络中一个重要的应用系统,它大大改善了学校教学、科研与管理的基础环境,在一定程度上反映出学校管理现代化的水平。

  • 系统需求

学生信息包括:学号,姓名,年龄,性别,出生年月,政治面貌,籍贯,家庭住址,

电话,E-mail等。试设计一学生信息管理系统,使之能提供以下功能:

(1)系统以菜单方式工作

(2)学生信息录入功能(学生信息用文件保存)

(3)学生信息浏览功能

(4)学生信息排序、查询功能

对信息进行排序,可以按学号,按姓名,按性别,按出生年月日,按籍贯进行查询

(5)信息统计

a)可以按性别,按出生年,按籍贯统计学生人数

b)可以按班级统计学生人数

c)可以按政治面貌统计学生人数

按班级统计学生党员人数,团员人数,以及所占比例,设计并输出统计报表。

(6)学生信息的删除与修改

设计要求:

*界面比较美观;

*有一定的容错能力,比如输入的成绩不在0~100之间,就提示不合法,要求重

新输入;

*最好用链表的方式实现。
