学生信息管理系统（论文）第 1 章绪论 1.1 引言随着科学技术的不断提高，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。随着计算机网络技术发展，Web 数据库技术已经成为应用最为广泛的网站架构基础技术在应用系统中，Web 提供了与用户进行通信联络的有效手段，利用 Web 技术，实现 Web 服务器与数据库系统的连接，完成对数据的处理与查询，用户可以通过操作简单易学的浏览器来查询处理所需要的各种数据。 1.2 问题的定义学生信息的管理是学校日常工作中的重要组成部分。高校招生规模的逐步扩大和认识制度的改革，在校学生人数将不断增加，而学生管理人员则相对减少。加上我国高等学校基层学生管理工作的头绪多，内容杂，管理细，要求高，传统管理办法已基本不适应新形势的要求。在校生的基本信息的管理，选课及成绩的信息的管理，学生学籍的管理，稍有不慎就会出现错误。同时学生成绩的手工登录与查询，是一项非常繁重而枯燥的劳动，每年课程的变化都需要重新规划，耗费许多人力和物力，而且会因人的情绪烦燥而出现失误。因此在计算机飞速发展的今天，应用数据库技术实现学生信息的管理是可行而必要的工作，实现高校学生信息网上管理，既能够提高工作效率，又可以提高工作水平。 1.3 系统介绍学生信息管理系统是典型的信息管理系统，本系统采用 B/S 的设计结构，其开发主要包括后台数据库的建立和维护以及前端应用程序的开发两个方面。对于前者要求建立起资料一致性和完整性强、资料安全性好的库。而对于后者则要求应用程序功能完备，易使用等特点。学生信息管理系统是一个学校信息化管理的重要组成部分，不但能实现学生网上成绩查询，同时也为学校管理者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学生信息，这种管理方式存在着许多缺点，如:效率低、保密性差，另外时间长了，将产生大量的文件和资料，这对于查找、更新和维护都带来了不少的困难。 1

1.3.1 系统目标学生信息管理系统（论文）现在我国的学校中学生信息的管理水平大多还停留在纸介质的基础上，这样的机制已经不能适应时代的发展，因为它浪费了许多人力和物力，在信息时代这种传统的管理方法必然被计算机为基础的信息管理所取代。采用计算机来实现学生信息管理系统归纳起来，好处大约有以下几点： 1．可以存储历届的学生信息，安全、高效； 2．只需一到二名信息录入员即可操作系统，节省大量人力； 3．可以迅速查到所需信息。 4．为将来学校上网做好准备。学校学生可以在任何一个角落查询自己的成绩信息，不受时间、地点限制。根据要求，本系统模块具体实现如下的功能： 1. 实现学生网上成绩查询的功能。学生可以在网上查询自已每门课的成绩信息。 2. 实现对学生个人信息查询的功能。学生可以在网上查询自已的个人信息。 3. 实现对学生课表查询的功能。学生可以在网上查询自已的课表信息。 4. 实现对学生用户密码修改的功能。学生可以在网上修改自己的用户密码。 1.3.2 业务流程图业务流程描述：用业务流程图描述现系统各项业务处理过程，并结合业务流程图详细准确地说明业务处理过程中数据的收集、输入、传递、存储、加工的方法、算法、输出的数量及形式等。现行系统的业务流程图是分析和描述现行系统业务的重要工具之一。其主要作用是：描述现行系统的业务情况以便于与管理人员交流，它是系统设计的前提和保证。业务流程图使用的符号：符号名称实体输入/输出的报表处理业务流向文档存储 2
