asp的新闻管理系统的设计与实现

摘要

利用ASP和SQL技术开发的新闻管理系统，实现了新闻的动态管理，使得对信息的管理更加及时、高效，提高了工作效率。

同时对系统的开发原理、系统的功能特点和设计方案进行了介绍。

【关键词】ASP，SQL，新闻管理，数据库

随着Internet的普及，越来越多的企业建立了自己的WWW，企业通过可以展示产品，发布最新动态，与用户进行交流和沟通，与合作伙伴建立联系，以及开展电子商务等。

其中新闻管理系统是构成企业的一个重要组成部分，它担负着双层作用，一方面可以用来动态发布有关新产品或新开发项目，另一方面又可以及时向顾客公告企业经营业绩、技术与研发进展、特别推荐或优惠的工程项目、产品和服务，从而吸引顾客，扩大顾客群。

传统的新闻管理方式有两种，一是静态HTML页面，更新信息时需要重新制作页面然后上传页面并修改相应，这种方式因为效率太低已不多用。

二是基于ASP和脚本语言，将动态网页和数据库结合，通过应用程序来处理新闻，这是目前较为流行的做法。

但是由于ASP本身的局限性使得系统有一些不可克服的缺陷，而采取了ASP.NET技术的系统性能上有了很大的改善，其主要表现在以下几方面：

1．由于ASP页面每次打开都必须经过先编译后解释的过程，所以页面在反复打开时速度没有任何提升，而ASP
