Abstract:

To manipulate the heterogeneous and distributed data better in the data grid, a dataspace management framework for grid data is proposed based on in-depth research on grid technology.Combining technologies in dataspace management, such as data model iDM and query language iTrails, with the grid data access middleware OGSA-DAI, a grid dataspace management prototype system is built, in which tasks like data accessing, abstraction, indexing, services management and answer-query are implemented by the OGSA-DAI workflows.Experimental results show that it is feasible to apply a dataspace management mechanism to the grid environment.Dataspace meets the grid data management needs in that it hides the heterogeneity and distribution of grid data and can adapt to the dynamic characteristics of the grid.The proposed grid dataspace management provides a new method for grid data management.

为了更好地管理和应用数据网格中大量分布异构的数据, 在对网格技术发展现状进行深入研究基础上, 提出基于数据空间概念的网格数据的管理架构.在此基础上, 实现了一个网格数据空间管理原型系统, 系统中将现有的一些数据空间技术如数据模型iDM、查询语言iTrails等与网格数据访问中间件OGSA-DAI相结合, 使用OGSA-DAI工作流来完成数据空间管理系统的数据访问、抽取、数据索引、服务管理和查询回复等一系列工作.实验表明数据空间管理机制在网格环境下是可行的, 数据空间管理系统屏蔽了网格数据的分布性和异构性, 且能够适应网格数据动态特性, 因此满足了对网格数据的管理要求.所提出的网格数据空间架构为网格数据管理提出了新的方法.
