针对模型驱动体系结构中的模型转换问题,提出一种从PIM关系类图到SQL关系PSM的二步转换法,通过依赖、泛化、关联3类关系的初步转换,使其脱离关系线,得到仪与属性类型相关的PIM类图,并对不同类型的属性制定相应的转换规则,利用一个具体示例展示了转换过程及其结果.实验结果表明,与简单的关联关系转换相比,该方法更全面,能够完整实现模型转换.

Aiming at the model transformation problem in Model Driving Architecture(MDA),a two step transform method is proposed,which transforms PIM relation diagram to SQL PSM.It makes the depend,inherit,associate away from the relation line to PIM class diagram by the first transformation.The PIM class diagram is only about with the type of attribute.The transformation rules to different attributes are introduced.A practical example is given to show the transformation process and result.Experimental results show that,compared with the simple association transformation,this method is more comprehensive and more material,the model transformation is realized more perfectly.
