【摘要】 数据集成是为了屏蔽数据的异构性,以一种统一的接口访问数据源中的数据。由于无结构化数据没有外在的模式定义,因此基于模式的集成不能适用于流媒体、图形、图像等无结构化数据的集成。该文借鉴面向对象建模方法的思想,提出了语义对象模型的概念,并基于该模型描述了一个集成应用系统的体系结构。更多还原

【Abstract】 Data integration is to shield the heterogeneity,to provide a uniform interface to a multitude of data sources.For not having scheme ,the integration of un-structured data,such as streaming media,graph,image,can not use the integration method based on schema.In this paper,borrowing some concepts from the object-oriented model,writers put forward the idea of semantic object model,and describe an integration architecture based on the model.更多还原
