摘　　要：模型转换是MDA的关键技术之一,变换工具通过输入源模型,执行变换定义,输出目标模型来实现模型的自动转换,从而将软件开发的焦点从编码迁移到建模上。QVT是OMG提出的用于书写变换定义的标准规范,介绍了QVT的组成和构架,给出了一个用QVT实现的可从UML模型转换到RDBMS模型的变换定义,最后对模型转换技术给软件工业带来的影响进行了分析和总结。Model transformation is one of the key technologies in MDA. To achieve model transformation, the transformation tool takes the source model, executes the transformation definition, and gives the target model as output, which moves the focus of work from programming to solution modeling. OMG advanced the QVT as a standard specification for writing transformation definition. Firstly, the composition and architecture of QVT is introduced. Then, a QVT-based transformation definition is put forward to map UML model to RDBMS model. Finally, what impacts will model transformation bring to software industry is analyzed and summarized.
