整体架构与实现校园网新闻发布系统 摘要 应用网络通信技术传达必威体育精装版动态，已成为今天通信中的重要组成部分，随着互联网的飞速发展，新闻在网络中的发布也越来越引起教育机构、政府及企业单位的高度重视。组建校园网新闻发布系统，快速传达校园内外必威体育精装版动态，有利于加强师生的互动性，拓展师生的生活视野。本文阐述了校园网新闻发布系统的需求及内涵，深入分析校园网新闻发布系统的体系结构及应用，最终讨论了新闻发布系统的编程技术与实现。编制校园网新闻发布系统应遵守软件工程的原则，本文从新闻发布系统设计、功能目标设计、具体页面的确定及数据库的设计等几个方面来说明新闻发布系统的技术与实现。 关键词 三层结构 ADO.NET The overall overhead construction and realizes the system of campus net newsissue ChengChengLi (Dept. of Computer and Information Science, Southwest Forestry College, Kunming, Yunnan, 650224, China) Abstract Applying the network correspondence technique informs latest development, has become the important part of the now days correspondence, along with the flying developing of the Internet, announce of news in network also causes educate organization, government and business enterprise units more and more value highly. Establishing the news announce system of campus net, informing latest development quickly outside or inside the campus, it is benefit to enhances the interactive of teachers and students and expands living visual field of teachers and the students .This text expatiates the needs and content of the news announces system of campus net, and goes deep into analyze system and applications of the news announce system of park net, and at the end discuss the plait distance technique of the system with realizes of the news announce system . Establishing the new announces system of campus net should obey the principle of the software engineering, this text explains the technique that news announce system with realizes from a few aspects as follows: such as the news announce system design、function target design、certain of concrete page and design of database and so on.
