摘　　要：传统的紧密耦合集成方法缺乏可扩展性和较强的语义表达能力。为此,提出了一种语义模型构建技术,并以语义模型来取代传统集成中的全局模式。语义模型的构建以资源描述框架和资源描述框架模式为基础,实现数据语义关系的形式化描述,以异构数据库数据到语义模型的两级映射方法为手段,保证数据的透明访问和模型本身良好的可扩展性。语义模型使得构建语义一致的全局数据视图成为可能。应用表明,该模型是可行而有效的。Traditional tightly-coupled integration method was devoid of sufficient scalability and semantic representation. To solve the problem, a semantic model construction method was proposed which was used as the substitute for global schema in traditional process, Resource Description Framework （RDF） and RDF Schema （RDFS） were served as the base for semantic model construction to implement the formal description of semantic relationship, Two-layer mapping method between heterogeneous relation data and the semantic model was adopted to guarantee the transparency access for the heterogeneous data and the scalability of the model. The semantic model has been applied in practice and proved to be effective in building the semantic-consistent global data view.
