| 摘 要： | 网格服务的一个重要目标是实现数据资源的共享,然而网格环境的复杂性阻碍了对数据的有效访问。利用中间件屏蔽底层的复杂性,实现对网格环境下跨平台,异构数据资源的统一访问是当前研究的重点。该文结合中科院科学数据网格项目的特点,阐述了在开放网格服务架构下用中间件来实现网格中数据的统一访问的原理,并给出了实现的方法。

| Abstract: | The most important goal of Grid is to enable sharing of resources.However,the complex circumstance in Grid has become an obstacle for accessing data fluently.Hence,using middleware software to realize unified access and integration for cross-platform ,distributed and heterogeneous data resources under grid environment become the hotspot of grid technical research.According to the characters in the Data Grid Project of the CAS,the paper presents a middleware software under Open Grid Service Architecture to realize the unified access in Grid environment and give the details of the implementation. |
