| 摘 要： | 网格技术是近年来新兴的一个研究热点,它使互联网上所有资源实现全面共享与协同工作,将整个因特网整合为一个巨大的超级计算机,为用户提供"即连即用"的服务.本文详细介绍了网格中间件OGSA-DAI和OGDA-DQP,并针对目前图书馆期刊信息整合的现状,利用网格中间件技术对各种期刊数据库进行整合,即利用OGSA-DAI对期刊数据库进行封装,通过OGSA-DQP进行统一检索,解决了目前在异构数据库整合中基于界面整合自治性差、稳定性不好的特点.

| Abstract: | Grid is one of the most attractive research fields recently,which enables all the distributed resources over the Internet widely working with sharing and collaboration each other.It makes the whole Internet as a super-computer and services users for "plug and play".In this paper,the grid middleware OGSA-DAI and OGSA-DQP are introduced firstly,then we give the method that through the encapsulation of all kinds of hetero-geneous,autonomous databases using OGSA-DAI,all kinds of journal databases bought by the library can be searched by OGSA-DQP.Using the grid middleware,the searching method is more independent and steady in heterogeneous databases. |
