摘要： 模型驱动方法解决了软件开发的效率低、可移植性差等问题，其中的模型转换是开发基于模型驱动构架(MDA)应用工具的关键技术。为此，在模型驱动方法的基础上，提出基于模式的平台无关模型到平台相关模型的模型转换方法，并根据该转换方法确立转换规则，在一个MDA应用系统开发实例中进行验证，实现从平台无关层模型到J2EE平台相关层EJB模型的转换。

Abstract: Model driven methods are to solve the low efficiency, poor portability in software development, model transformation is the key technology in development of application tools based on Model Driven Architecture(MDA). This paper introduces the theory about MDA technology, proposes the model transformation method of Platform Specific Model(PIM) to Platform Specific Model(PSM) based on pattern, according the transformation method to establish the transformation rules, it is verified in an instance of MDA application development, this method realizes the transformation from platform independent model to enterprise Java bean model of J2EE in platform specific model.

Key words: Model Driven Architecture(MDA), meta model, domain model, Platform Specific Model(PSM), model transformation
