网络教学平台及数据共享系统
摘 要
随着教育信息化的发展，越来越多的学校开展了网络教学，开发网络教学平台显得
极为重要。本网络教学平台利用.NET技术结合XML的灵活性构建了一个三层结构模式的
教学平台。此系统以数据库SQL Server和XML为依托，采用比较先进的.NET技术，使用
全新的面向对象语言C#，结合ASP. NET，运用Web服务设计完成。系统分为用户层，功
能层和数据层三层。用户层以界面的形式增加交互应用；功能层将系统划分为许多功能
模块，以组件的形式完成应用程序的运算，使得系统结构更模块化；数据层存储系统信
息。功能层通过ADO.NET实现对数据层的数据快速访问，数据层全部采用存储过程来实
现对底层数据的操作。同时数据层采用XML进行灵活的数据存储和动态更新，实现系统
快速便捷的功能，缓解数据库压力。采用.NET技术实现了程序和代码的分离，以面向对
象语言C#开发组件，实现复杂的逻辑,使得程序代码更安全,执行效率也更高，且容易配
置成分布式系统。通过Windows身份验证增加系统的安全性。

Abstract
With the development of educational informationization, network teaching appears in
more and more school. This System used a 3-layerarchitecture teaching platform based
on .NET technique. The system adopts SQLServer,.NET,C#,XML and web service.The system
architectur divides into the user level, the function level and data level.
The user level increases by the contact surface form alternately applies.
The function level divides the system into many functions modules,completes the application
procedure by the module form the operation,causes the system structure modular; Data level
memory systeminformation. The function level through the ADO.NET realization logarithm
accordingto the level data fast access,the data level completely uses thememory process to
realize to the first floor data operation. Simultaneously the data level uses XML to carry on the
nimble datastorage and the dynamic renewal,the realization system fastconvenient function,
alleviates the database pressure. Used .NET to realize the procedure and the codeseparation,by
the object-oriented language C# development module,realized the complex logic,caused the
procedure code safely,carried out the efficiency also high,also was easy to dispose the
distributional system.Through Windows identification authentication increase system
security.

1. 概述
1.1 问题的提出
在这个知识经济时代，对于我们学生来说，学习节奏都加快了！快速获取知识，高效
率的学习已经变的非常重要了！正是基于这样一个观点，我们开发了网络教学平台及数
据共享系统。
1.2 系统性能需求
网络教学平台及数据共享系统包括系统管理模块，学校管理模块，教师管理模块，学
生管理模块，综合查询模块。
数据手动/自动录入，数据查询，修改，删除。同时对数据维护和备份。
对相关数据生成报表进行综合分析
连接INTERNET和移动通信的功能
根据学校的行政体系安排工作日程的功能
根据教师和班级的信息自动排课的功能
在线测试和考试中心功能
XML支持
RSS新闻聚合功能
功能较完善的网站流量统计系统
系统要求
保密性：设置各级用户，用户对应不同的操作，只有管理员具有全部操作权限。
及时性：要求发送短信和邮件要及时，时限不能超过一小时。
正确性：系统数据要求较高的正确性。以保证学校教学的正常运行。
