摘要
多数据库系统是实现多个分布的异构数据源数据共享和互操作的有效途径．首先介绍了一种基于ＣＯＲＢＡ的多数据库系统体系结构模型，然后提出了一种面向ＸＭＬ的公共数据模型ＸＩＤＭ，这些模型能很好适应多数据库系统分布性、自治性和异构性等特点．还对基于这些模型所实现的一个多数据库原型系统Ｐａｎｏｒａｍａ进行了介绍．
A multidatabase system is an effective approach to implement data sharing and interoperability among many distributed and heterogeneous data sources. In this paper, a CORBA-based architecture model of multidatabase system is firstly introduced. Then, an XML-oriented common data model, named XIDM, is presented. These models conform to the characteristics of multidatabase systems, such as autonomy, distribution and heterogeneity. Panorama, a prototype system on the basis of these models, is introduced at the end of the paper.
