计算机软件数据整合虚拟数据库体系研究分析

Research and analysis of virtual database system for computer software data integration

本文主要针对计算机软件数据整合虚拟数据库体系展开深入研究,先阐述了数据整合系统设计,然后又针对此系统提出了几点关键技术,如数据集元数据全局模式、主题知识元数据集元数据全局模式、局部模式中元数据的获取、数据源包装器、分布式数据源的调度策略,通过以上几点关键技术,促使资源有效利用。

This paper mainly focuses on the virtual database system of computer software data integration.Firstly,it describes the design of data integration system,and then puts forward some key technologies for this system,such as global schema of metadata of dataset,global schema of meta data of subject knowledge metadata,acquisition of metadata in local schema,wrapper of data source,and distributed data source Through the above key technologies,it can promote the effective utilization of resources.
