摘要

异构数据源的有效集成已成为各领域研究中最紧迫的挑战;比如高能物理、天文学和生命科学。在这个演讲中,我们提出了一个使用Globus Toolkit和OGSA-DAI的数据集成系统。为了在多个数据库之间关联相关数据,我们引入了基于它们的域本体的元数据。使用该系统,可以创建一个数据库访问流,将一组查询描述为工作流,并且可以在不知道数据库位置和模式的情况下跨数据库进行查询

A Grid Environment for Data Integration of Scientific Databases
Effective integration of heterogeneous data sources has been studied as the most pressing challenge in various fields; such as, high energy physics, astronomy, and life sciences. In this talk, we present a data integration system by using Globus Toolkit with OGSA-DAI. For associating related data among many databases, we have introduced metadata based on their domain ontologies. Using the system one can make a database access flow for describing a set of queries as a workflow, and can query across the databases without aware of their locations and schemas
