Abstract: A method for MDA implementation, especially on the EJB platform, is proposed in the paper based on pattern and action semantics. First, the applications of patterns during different phases of MDA implementation are illustrated. Then the implementation method is described with action semantic meta language. Last, the method is proved feasible with a bank model example. The method is considered to be of evident significance to the application of MDA specification.

摘要： 基于模式和动作语义，结合EJB平台，提出了MDA的一个实现方法。说明了模式在MDA设计、映射、实现阶段的应用方法与步骤，采用动作语义元语言给出了对该方法的描述，最后，结合具体实例说明了该方法的可行性。
