IIE环境下数字民航的虚拟数据仓库研究

本文结合现代企业信息网的特点,通过研究数据仓库体系结构和数据仓库层次数据模型,将数据库中数据以XML的形式,通过虚拟网络视图完成局域数据的集成与共享.进而通过建立基于虚拟网络视图的虚拟数据仓库,提供了数字民航在IIE环境下分布异构数据源的集成平台,介绍了虚拟数据仓库的体系结构和特点,并提出了分布异构环境下数字民航的数据集成框架结构.

Research on DATAIR's Virtual DataWarehouse in IIE Environment

With considering of characters of modern enterprise information network, the authors are doing some research on the data warehouse' structure and data model. Through the methods of markup data of databases in XML format and the Virtual Net View, the local data's integrity and share is realized. And then through the Virtual Net View based Virtual DataWarehouse,the integrated platform of DATAIR's distribute and heterogeneous data sources in IIE environment has been established. At the end, the structure and characters of Virtual DataWarehouse is gave and the data integration architecture of DATAIR which was build in distributed and heterogeneous environment is proposed.
