基于本体的异构数据源集成系统分析与设计

Analysis and Design of Heterogenous Database Integration System Based on Ontology

分析了现有的数据集成方式,针对集成中的语义异构问题提出了一种基于本体和XML的集成系统框架,其中包括应用层、中间件层和数据源层3个层次,并给出了关键模块的设计,包括中介器、本体库和包装器。结合航空装备信息的特点,介绍了该框架在航空装备信息集成系统中的具体应用。

Based on the different kinds of data integration methods,this paper brings forward an ontology-and-XML-based data integration framework for eliminating the semantic heterogeneity,including application layer,middleware layer and database layer.It expatiates the pivotal technology of implementation and gives an application instance in the integration information system of aviation equipment.
