摘要：学籍管理信息系统是高校管理的重要组成部分，为老师、同学提供存档、查询等手段。

根据教学安排，我们有两周的时间进行学籍管理信息系统课程设计，我们小组团结一心，分工明确，积极讨论，终于在组员的努力下及老师的指导帮助下，我们顺利完成了本次课程设计，系统包括学生资料设置，成绩设置，成绩、排名查询，修改资料关键字：系统查询课程设计论文管理目录第一章绪论-------------------------------------------------（1）1.1 课程设计背景 (1)1.2 课程设计目的 (1)1.3 课程设计思路 (1)第二章系统总体规划-----------------------------------------（2）2.1 前期准备 (2)2.2系统功能 (2)第三章系统分析设计-----------------------------------------（3）3.1 建立MFC主界面及代码设计 (3)3.2 学生资料设置及代码设计 (10)3.3学生成绩设置及代码设计 (19)3.4查询功能及代码设计 (28)3.5修改密码功能及代码设计 (30)3.6删除功能及代码设计 (34)3.7修改功能及代码设计 (36)第四章界面设计与实现----------------------------------------（37）4.1 学生信息管理系统 (37)4.2 学生资料设置 (37)4.3 成绩设置 (38)4.4 学生资料显示 (38)4.5 成绩显示 (39)4.6 修改密码 (39)总结---------------------------------------------------------（40）工作安排-----------------------------------------------------（43）参考文献-----------------------------------------------------（44）第一章绪论1.1课程设计背景经过一个学期对《C++程序设计》的学习，学习到了基本的理论知识，了解到了C++语言程序设计的思想，现在把这些知识运用到实际中来。

学籍管理信息系统是高校管理的重要组成部分，它能够为用户提供充足的信息和快捷的查询手段。

使用计算机对学生资料、成绩信息进行管理，能够极大的提高学生管理的效率，节约教育经费，这也是适应学校信息化建设发展趋势的重要因素。

因此我们有必要开发学籍管理信息系统。

1.2课程设计目的全面系统的学习面向对象程序设计的基本概念、基本语法和编程方法。

正确理解掌握C++面向对象程序设计的基本特性：类、对象、继承与派生、多态、虚函数、模板、流类库等。

遵循软件过程的各个环节进行系统分析、设计、实现、集成、测试，并相应给出软件规格说明书等制品。

了解当前常用的软件开发工具（Visual C++），要求熟练掌握基于MFC的程序设计，培养解决实际问题的能力。

1.3 课程设计思路实现学生基本情况的录入、修改、删除等基本操作；能实现学生成绩的录入、修改、删除等基本操作；能方便的对学生的各个学期成绩进行统计；能具有成绩统计、排名等功能；可行性分析由于本系统管理的对象单一,都是在校学生，且每个数据内容具有较强的关联性，涉及的计算过程不是很复杂。

第二章 系统总体规划2.1 前期准备学习C++6.0课本理论知识，查找、搜集相关资料，讨论出具体思路、方法，在整个过程中周老师给了我们必不可少的许多指导，使我们能够顺利地完成前期各项工作。

2.2系统功能基于系统需求分析，该系统具有以下基本功能：用户管理：管理系统操作人员，设置操作人员账号、密码、用户资料等。

用户资料：学生通过登录，可以查询到自己的资料、成绩、排名，同时可以修改密码。

成绩管理：管理员根据学生成绩保存到系统中，同时可计算出综合排名、平均分等信息。

基础数据管理：维护学生资料，主要包括院系、专业设置，联系方式、学号等个人信息设置等。
