MDA中PIM到PSM变换规则的研究

Research on the Rules for the Transformation from PIM to PSM in MDA

在MDA开发模式中,将模型分为PIM(平台独立模型)和PSM(平台相关模型),其目的在于通过一定的变换规则实现PIM到PSM的自动转换,从而可以方便地生成应用程序代码以及测试框架。要实现PIM到PSM的自动转换,关键在于变换规则的精确定义。本文对变换规则提出了一种形式化的定义,并结合特定的PSM给出了一个具体的转换实例,最后给出在此基础上设计的平台的实践结果。

There are two kinds of models in MDA： PIM and PSM. We can transfer PIM to PSM automatically using some special transformation rules, so that we can generate application codes and test frameworks easily. However the trans- formation from PIM to PSM depends greatly on the accurate definition of the transformation rules. This paper proposes a transformation rule and gives an instance based on a special PSM. Finally the paper gives the practical result of the platform based on the rule.
