Libarary Uniform Search System Of Beijing University Of Technology

Since 1990s,with the rapid evolution of the internet and increasing popularization of the high technology, especially the rising of the knowledge economy, people know gradually that information is the base of the knowledge economy, and he will take the initiative of developing economy if he controls information. So the ordinal organization of the internet information has arose more and more regard of all countries. Under this conditions, digital library emerged as the times require, and grdually became a hotspot which all countries devoted to. As the important carrier of the knowledge economy ,digital library is the important part of the country's information basic establishment. Now digital library has been a important token of estimating a country's information basic level and become one of the focus which all countries' culture and technology's competition.In these years, under the driver of education information and scientific research information, colleges library and common library of our country has boosted the development of the information rapidly, especially colleges library of our country's development is the most success. Most of the colleges developed good-sized digital information resource by introducing into and self-create database, provided more and more convenient information service through CWISs(Campus-Wide Information Systems),internet and digital reading room, and improved education and scientific research's procession of our colleges rapidly.This thesis brings forward a fire-new resolvent to uniform search of different platforms and isomerous data source in the course of developing digital libraries of all colleges. And this paper comes from the requirement in the course of developing digital libraries of Beijing Polytechnic University and accords with the actual requirement of the development of our country' digital library of colleges. It conforms ulteriorly all kinds of existing resource, brings all kinds of databases, which have different sources, different structures and different usages, into a uniform search platform, so that users can get their information conveniently.This paper introduces J2EE criterion, character of J2EE distributed application system architecture and the technology trait of BEA's Weblogic which supports J2EE truss. This paper also describes detailedly uniform search system which based on J2EE truss and its design idea, total truss, each hiberarchy's concrete design and corresponding realizing.
