网格环境中的多维数据信息集成访问研究

在实际的应用环境中，网格数据管理需要集成已有的信息资源，并通过发布领域相关的元数据获得领域内信息数据的集成访问。该文以油气勘探开发领域内的信息资源为主要研究对象，在分析了它的多维度、多层次、结构化特点的基础上，设计了一种对已有数据库集成访问的网格构件IAC。同时，给出了描述IAC代理数据内容及映射关系的元数据模式，并讨论了该构件在应用网格体系结构中的作用。

Research on Integration and Access for Multi-dimension Data Information in Grid

In a specific application domain,the grid data management needs to integrate and access existing information resource by publishing domain-specific metadata.In this paper,the information resource in the field of oil & gas exploration and development is regarded as main study object.Based on its multi-dimensional,multi-tiered and structured characteristic,a grid component is designed to integrate and access existing databases.It also depicts the metadata schema that describes the database contents and mapping schema and discusses the component's role in application grid architecture.
