摘要： 网格的核心任务是管理分布在Internet广域环境中的各种类型的软硬件资源，为基于Internet的分布式应用提供一个统一的、虚拟的共享资源的计算平台。如何将数据库资源并入现有的网格架构，满足更加广泛的网格应用的数据访问需求，已经成为一项亟待解决的课题。文章提出了一套网格环境中的数据发布系统的设计方案，以网格服务的形式封装对数据库的访问，实现跨越异构网络环境、异构操作系统环境和异构数据库平台的统一访问模式，从而将数据库资源加入到网格环境中。

Abstract: Grid technology aims to help eliminate isolated island of hardware and software resources, so that users can achieve the sharing and managing of many kinds of resources and easily provide services on the entire grid. Currently, the great challenge from the requirements of many popular grid applications is how to share and manage data resources in grid architecture. This paper introduces the architecture design to realize publishing data resources efficiently in grid environment, and then applies this idea in the implementation of data publishing system for scientific data grid.

Key words: Data publishing, Grid, Grid service, Data grid
