摘　　要：模型转换是MDA(Model Driven Architecture)的核心技术之一,也是目前MDA研究的热点。查询/视图/转换(QVT)是OMG(Object Management Group)提出的模型转换的标准化方案。介绍编织和已有的各种模型转换技术,以及这些技术存在的缺点。同时介绍了基于QVT的模型驱动构架和属性结构,从而满足一致性和消解的要求。在语言维上,对QVT的三种语言分别进行了介绍,并根据规则实现了关系到核心语言的转换。FMTP系统基于QVT规范和Kermeta语言中的模型转换功能,通过对QVT核心分层,设计了基于映射的四层QVT结构的模型转换工具。Model transformation is one of the core techniques in MDA （ Model Driven Architecture） and is the research hotspot in this area. OMG （Object Management Group） advanced Query/Views/Transformations （QVT） as a standardized scheme of the model transformation. This paper introduces weave and existing model transformation techniques as well as the defects of them. To satisfy the demand of conformance and dissipation, the paper introduces MDA and the structure of attributes based on QVT. In language dimensions, three languages of QVT are introduced respectively. According to the transformation rules, QVT implements the transformation from relation language to core language. Based on QVT standard and the function of model transformation in Kermeta Language, FMTP system designs a model transformation tool of a four-layer QVT structure based on mapping by delaminating the core of QVT.
