【摘要】 本文从研究信息检索技术入手，探讨了在UNIX和Windows NT网络环境下，应用不同中间件，实现Web信息服务系统的解决方案。本文的主要内容是描述一个国家级的气象卫星资料Web检索系统的方案设计和实现。该方案基于国家卫星气象中心实际的网络环境、软硬件平台及气象卫星资料存档系统的建设，采用Web浏览器/Web服务器/Web数据库三层体系结构，实现并发布了基于Internet/Intranet的气象卫星资料编目检索业务系统。检索系统是建立在HP_UX操作系统上，以Netscape Enterprise Server为Web服务器，Netscape公司的LiveWire为中间件，Sybase为数据库管理系统。检索系统重点突破了可视化地图框定检索关键技术，实现了快视图浏览、编目检索、各类客户端可控制的图像动画等功能。更多还原

【Abstract】 The technic of information retrieval is being studied at first, then the solution of implement the Web Information Services System under UNIX and Windows NT network environment by various middleware are discussed. The main content of this treatise is to descript the detail solution of designing and implementing the national level Web retrieval system of data from meteorological satellite. This solution is based on the existing network environment , the software and hardware platform , and the Archive System construction of NSMC(National Satellite Meteorological Center), and is implemented by the three Layer System Structure Web Browser ,Web Server and Web Database. It also implemented and published the Internet/Intranet based catalogue retrieval vocational system of data from meteorological satellite. The retrieval system is being developed on HP_UX operation system. The Netscape Enterprise Server acts as its Web Server, the LiveWire of Netscape acts as its rniddleware, and Sybase acts as its DBMS (Database Management System). Furthermore, the breakthrough of the retrieval system is the key technology of visual retrieval with marking on the map. It allows us to make the retrieval condition by dragging the mouse on the map displayed on the user’s screen. The retrieval system also implemented the functions of quick-view image browsing, catalogue retrieval and client-side manipulated animate of a series of images, etc.更多还原
