跨库检索系统的实施与研究

本文借鉴元搜索引擎的原理,采用web检索的方式,建立了一个基于java技术的可跨平台的跨库检索系统模型,并就其设计思想、系统结构和实现要点进行了详细介绍。能满足用户对数据库跨库检索和并发检索的需要,通过它能同时检索到多个数据库中的内容,弥补目前大多数搜索引擎达不到的功能。

This paper demonstrates the design thought of inter database retrieval system using the principle of meta search engine for reference and the web search method to build a search system model, it bases on JAVA tech- nology for cross-platform system, and detailedly introduces the design method and the system architecture and the main point of system implementation. The system is an important research project in the field of Web database retrieval, it can meet the user＇ Ms demand for inter database retrieval and concurrence retrieval, and it can retrieve the content of many databases at the same time. The system realized some functions which many search engines nowadays fail to achieve, and it has theoretical and practical value,
