【摘要】 二十一世纪是知识经济的世纪，是网络化的世纪，我国教育的发展迎来了新的机遇和挑战。通过采纳高效的计算机技术、先进的网络技术和丰富的应用软件，并且结合教育信息化的理念，数字化教学逐渐向传统教学中渗透，而家长与学校的交流也是数字化教学过程中的一个重要环节，基于这样的背景，我们设计和开发了数字化教学中家长与学校互动平台。 浏览器／服务器结构实现了“瘦”客户端，使得整个系统的维护量很少，而且系统减少了向数据库服务器发送SQL请求，使系统性能更佳。另外，这种结构能够实现更为细致的授权定义，从而增强整体系统的安全性。这种结构也体现了分布式应用系统的含义，分布式应用系统结构把系统不同的运作部分分布到独立的机器中，使整个应用系统的延展性大为提升，已成为众多厂家争相采用的新型体系结构。 本文对浏览器／服务器结构和以前的网络计算模型进行了分析比较，阐述了浏览器／服务器结构的工作原理及其特点，说明了平台所选用结构的合理性和优越性。另外，本文对开发家长与学校互动平台所采用的ASP．NET技术、ADO．NET数据访问技术、C#、组件技术以及XML技术等都进行了详细论述，说明平台所采用技术的先进性、优越性和适用性。 本平台实现了信息浏览与查询、网上讨论、留言等多种功能，并且给管理员提供了基于角色的平台管理功能，在平台的吸引力和亲和力等方面也做了很多工作，对于家长和学校相互交流的一些特殊要求给予了充分考虑。本平台提高了家长与学校相互交流的效率，是一个基于互联网的、功能完善的、扩展性好的、安全可靠的、实用性强的家长与学校之间相互交流的平台。更多还原

【Abstract】 The twenty-first century is the century of knowledge economy and network. The education in our country meets new chances and challenges. Integrated the theory of education informationize, E-teaching is gradually penetrating to traditional education by using effective computer technique, advanced network skill and abundant application software. And the communication between parents and school is an important component of E-teaching. Based on the background, the interactive platform between parents and school is designed and developed.The "thin" client of the B/S structure makes much less system maintenance and reduces the SQL requires to database server. So the system performance reaches to the best. Furthermore, the structure is capable of making authorization and definition more particular so as to enhance the system security. The B/S embodies the definition of distributed application system. The distributed application system structure putts different running parts to independence machine result in great increase of the system ductility. So many enterprises strive to adopt the novel structure.The disciplines, characteristics of the B/S and comparison to old network computation models are deeply analyzed in this thesis. The rationality and superiority of the structure on the developed platform is also depicted. And ASP.NET, ADO.NET, C#, component and XML are discussed in details. So the techniques in the work possess advantages, superiorities and applicability.The following functions are implemented on the platform, information browse and retrieve, online debate, message and roles based platform management for administrator. Many works are focused on platform’s attraction and appetency. Simultaneously, a lot of considerations are given to some special demand with respect to the communication between parents and school. Anyway, this platform increases the communication efficiency. And it is an Internet based platform with perfect functions, strong expansibility and practicability and reliable security.更多还原
