摘    要
21世纪，人类社会已进入崭新的信息化时代，信息技术正以前所未有的速度发展,人们对信息的交互需求也与日俱增。无线通讯技术以及手机终端的发展，从一定程度上满足了人们的需求，人们随时随地上网已经基本实现。首先，无线通讯技术的发展使基于WAP方式的信息浏览查询存在技术前提，这也是我们系统存在的前提；其次，随着无线通讯技术以及手机终端的发展，在当前的无线网络环境下，通过本信息发布系统，人们可以自由发布信息和查询信息，从而实现随时随地的信息交互。结合系统开发所需要的及现行的数据管理技术，系统采用了tomcat＋My eclipse +SQL server 2005数据库进行开发，开发语言为java + WML + WML script。系统完成就酒店、景区等信息的发布，管理，维护等功能，并实现了Internet WEB与WAP两种方式对信息的浏览查询。系统以提供操作简单方便、快捷，易懂易用为开发目标，用户界面设计简洁，操作使用方便，及具有高效的数据处理能力。而SQL SERVER 2005数据库以其强大的数据管理功能保证用户数据的稳定和安全。

Abstract
In the 21st century, it is an information age, in which the information technology develops more rapidly than ever before. Besides, the interaction between people and their need for information are increasing correspondingly. The development of the wireless communication technology and the mobile terminal has satisfied such kind of  needs at a certain extent, and people's access to network in anywhere and at anytime has came true. Firstly, the wireless communication technology provides the precondition to information browsing and querying which bases on WAP mode, and it is also the precondition to our system. Secondly, as the development of wireless communication technology and the mobile terminal, people can release and query information freely. And through this middle system in the wireless environment, people can obtain information in anywhere and at anytime through wireless net and mobile terminal. Combinated the needs of middle system development with current data management technology, the system is developed by using tomcat＋Myeclipse + SQL server 2005 in java & WML &WML Script language. The system has the function of information release, management and maintenance, and two modes of information access have been implemented, which are WEB and WAP. The purposes of this system are easy handling, easy studying and understandability. So, the user interface is terse and it is very convenient to handle. And more, the system has strong data processing ability. And the SQL SERVER 2005 ensures the stabilization and security through its powerful data management ability.
