学生信息管理系统java课程设计(含源代码)

JAVA 程序设计课程设计陈述宇文皓月课题: 学生信息管理系统姓名：学号：同组姓名：专业班级：指导教师：设计时间：目录1、需要实现的功能32、设计目的3 1、功能模块划分32、数据库结构描述43、系统详细设计文档64、各个模块的实现方法描述95、测试数据及期望结果11一、系统描述1、需求实现的功能1.1、录入学生基本信息的功能学生基本信息主要包含：学号、姓名、年龄、出生地、专业、班级总学分，在拔出时，如果数据库已经存在该学号，则不克不及再拔出该学号。

1.2、修改学生基本信息的功能在管理员模式下，只要在表格中选中某个学生，就可以对该学生信息进行修改。

评阅意见：评定成绩：指导老师签名：年月日1.3、查询学生基本信息的功能可使用“姓名”对已存有的学生资料进行查询。

1.4、删除学生基本信息的功能在管理员模式下，只要选择表格中的某个学生，就可以删除该学生。

1.5、用户登陆用分歧的登录权限可以进入分歧的后台界面，从而实现权限操纵。

1.6、用户登陆信息设置可以修改用户登陆密码2、设计目的学生信息管理系统是一个教育单位不成缺少的部分。

一个功能齐全、简单易用的信息管理系统不单能有效地减轻学校相关工作人员的工作负担，它的内容对于学校的决策者和管理者来说都至关重要。

所以学生信息管理系统应该能够为用户提供充足的信息和快捷的查询手段。

但一直以来人们使用传统人工的方式管理文件档案、统计和查询数据，这种管理方式存在着许多缺点，如：效率低、保密性差、人工的大量浪费；另外时间一长，将发生大量的文件和数据，这对于查找、更新和维护都带来了很多困难。

随着科学技术的不竭提高，计算机科学日渐成熟，其强大的功能已为人们深刻认识，它已进入人类社会的各个领域并发挥着越来越重要的作用。

作为计算机应用的一部分，使用计算机对学校的各类信息进行管理，具有手工管理无法比较的优点。

例如：检索迅速、查询方便、效率高、可靠性好、存储量大、保密性好、寿命长、成本低等。

学生信息管理系统完整源代码+mysql文件

数据库所用的数据自己导入MYSQL5.5，Navicat8就可以用了。

C语言学籍管理系统(内含源代码)

学籍管理系统一、系统简介设计一个基于结构体数组的学生学籍管理系统，能实现对学生学籍信息进行录入，修改，删除，查询和输出等基本操作二、需求分析学籍管理系统应该实现以下功能：1、能录入学生的基本信息，包括学号，姓名，专业，年级，性别和出生日期信息，保存到结构体数组中。

2、能根据输入的学号查询学生，进行信息的修改。

3、能根据输入的学号从结构体数组中删除学生的记录。

4、实现查询功能，能根据输入的学号或年级在屏幕上显示相应的学生信息。

5、能在屏幕上以列表的方式输出所有学生的信息。

三、概要设计1、系统功能根据项目的开发要求，本系统划分成六个主要功能模块：录入学生信息模块、修改学生信息模块、删除学生信息模块、查询学生信息模块、输出模块和推出模块。

系统功能机构图如下：2、重要数据的数据结构设计学生学籍的记录项用结构体Stu message表示，包括6个属性，stuno,name、spec、grade、sex、birthday 分另U代表学生的学号、专业、年级、性另U和出生日期，其中birthday 类型为自定义的结构体类型Date.Struct stumessage {Char stuno[11]: // 学号Char name[9]: // 姓名Char spec[2]: // 专业Char grade: // 年级Char sex : // 性别Stuct date birthday: // 出生日期}；日期类型date包括三个属性，分别代表年、月、日Struct date{int year : // 年Int month: //Int day: // H｝；3、函数设计学籍管理系统程序采用了结构化程序设计的思想，由1个.h 头文件和3个C源文件组成。

程序中除了主函数外，共设计了以下14个函数，分别包含在3个.c源文件中。

以下是这些函数原型及功能设计。

(1) void sysinfo(void)函数功能：在屏幕上输入系统及信息并等待用户响应。

php学生信息管理系统源代码

php学生信息管理系统源代码PHP学生信息管理系统源代码是一种基于Web技术的信息管理系统，可以帮助学校或教育机构管理学生信息，包括个人基本信息、课程成绩、考勤记录等。

该系统使用PHP语言编写，采用MySQL 数据库作为数据存储，具有良好的可扩展性和易用性。

该系统的主要功能包括：学生信息管理、课程信息管理、成绩管理、考勤管理、教师管理、班级管理、权限管理等。

下面对这些功能进行详细介绍。

一、学生信息管理学生信息管理是该系统的核心功能之一，它包括对学生基本信息的添加、修改、删除、查询和导出等操作。

管理员可以通过该功能完成对学生信息的全面管理，包括学生的姓名、性别、出生日期、联系方式等基本信息，以及学生的班级、专业、入学时间等详细信息。

同时，管理员还可以为每个学生上传照片，方便识别和管理。

二、课程信息管理课程信息管理是该系统的另一个重要功能，它包括对课程的添加、修改、删除、查询和导出等操作。

管理员可以通过该功能完成对课程信息的管理，包括课程名称、课程编号、授课教师、学分、学时等详细信息。

同时，管理员还可以为每个课程设置课程目标、教学大纲、教学计划等内容，方便学生和教师了解课程的内容和要求。

三、成绩管理成绩管理是该系统的重要功能之一，它包括对学生成绩的录入、修改、查询和导出等操作。

管理员和教师可以通过该功能完成对学生成绩的管理，包括成绩的录入、审核、统计和分析等。

同时，系统还支持成绩的按课程、按学生、按班级等多种方式进行查询和分析，方便学校或教育机构对学生的学习情况进行全面监测和评估。

四、考勤管理考勤管理是该系统的另一个重要功能，它包括对学生考勤记录的添加、修改、查询和导出等操作。

管理员和教师可以通过该功能完成对学生考勤记录的管理，包括考勤的录入、审核、统计和分析等。

同时，系统还支持考勤的按日期、按课程、按学生、按班级等多种方式进行查询和分析，方便学校或教育机构对学生的出勤情况进行全面监测和评估。

五、教师管理教师管理是该系统的重要功能之一，它包括对教师信息的添加、修改、删除、查询和导出等操作。

[工学]学生信息管理系统完整源码

学生信息管理系统完整源代码注：本系统采用C/S结构，运用Java GUI知识编写，数据库为SQL SERVER 2005，没有采用典型的三级框架结构，所以代码有冗余，仅供参考。

一、数据表及数据源首先创建数据库，包含数据表如下：数据库创建完成后，新建一个名为SIMS的数据源，不会建数据源的同学可以在去搜索创建数据源的详细步骤，这里的数据名称一定要为SIMS，否则在以后程序连接数据库的语句中会出现错误。

二、操作演示三、代码部分创建Java工程，创建名称为SIMS的包，一下Java类均包含在一个包内。
