摘　　要：为有效集成分布异构的关系数据资源,提出了一种基于本体的关系模式重构方法,以领域本体作为模式重构的概念集,通过本体的推理能力实现模式的重构。为了描述重构模式,提出了一种重构模式描述语言RSDL(Refactored Schema Description Language)。重构模式可以为分布异构关系数据源的有效集成提供逻辑视图。For the sake of integrating the distributed and homogenous relation resources effectively, this paper presents a method of refactoring relation schema based on ontology. Using the domain ontology as the concept set, this method can refactor the schema by the reasoning ability of the ontology. A refactored schema description language is also introduced to describe the refactored schema. Refactored schema can provide logic view to the effective integration of the distributed and homogenous relation resources.
