一. 课程设计的目的
学生信息管理系统以计算机为工具,通过对教务管理所需的信息管理,把管理人员从繁琐的数据计算处理中解脱出来,使其有更多的精力从事教务管理政策的研究实施,教学计划的制定执行和教学质量的监督检查,从而全面提高教学质量。
(1)本系统是运行在windowsXP操作系统环境下的多台计算机构成
的局域网,主要业务流程如下:
·按某学生某学期,学年考试及补考成绩。
·按每学期各年级班学生考试成绩自动生成补考名单,科目。 ·按每学期各年级学生考试成绩自动生成某课程统计分析表。 ·按同一年级学习成绩进行同一课程不同班级间成绩比较。
(2)功能要求
·学生档案管理: 学生的基本信息
·学生成绩管理: 学习成绩,补考成绩; ·毕业生学籍处理:毕业处理
(3)功能概述
(3.1)学生信息的管理:
即录入、修改、查询、输出学生档案信息,这些信息包括学生家庭住址、联系电话、出生年月等信息。
(3.2)学生成绩管理:
即录入修改、查询、输出学生各门课程的成绩信息,并支持按年级、班级等条件的统计、查询、报表输出。

(2)可行性分析
管理信息系统的任务事:在充分认识原信息的基础上,通过问题的识别,可行性分析,详细调查,系统化分析,最后完成新系统的逻辑方案设计,或者称逻辑模型设计,逻辑方案事系统分析的任务,解决“做什么”的问题,物理方案事系统设计的任务,解决“怎么做”的问题。开发新系统的要求往往来自于对原有系统的不满,原系统可能事手工系统或者事正在运行的信息系统。由于纯在的问题可能含糊不清,这就要求系统分析员针对各种存在的问题出示要求作出识别,进行问题定义通过可行性分析确定开发系统的必要性。
(3)需求分析
建立学生信息管理系统,帮助广大教师提高工作效率。通过本系统软件,能帮助工作人员利用计算机,快速方便的对学生信息进行管理、输入、输出、查找等操作,使散乱的档案能够具体化、直观化、合理化。 2.2概念结构设计 E-R:(1)毕业生学籍管理(2)学生-选择-课程 2.3逻辑结构设计
