【摘要】 目前模型驱动架构(MDA)中的平台无关模型(PIM)对构件的描述缺少精确的形式化语义,对构件的建模支持已经远远落后构件技术的发展。结合模型驱动和构件开发的优点,通过UML的扩展机制,提出了一个基于MDA的构件开发模型框架,扩充了对构件模型的建模开发,使得MDA对构件描述的PIM层更为精确,从而达到MDA和构件开发相结合以改进软件开发的目的。更多还原

【Abstract】 Currently, Model Driven Architecture (MDA)’s independent platform model (PIM) is lack of accurate description in the formal semantics for component, the support on modeling of components has far behind the development of component technology. Combining the merit of the driver component with that of model development, and adopting the UML Profile, we prose a component development framework based on MDA, which expands component modeling development, makes description about the component in PIM layer using MDA more precisely, and to achieve the purpose of improving software development through the combination of MDA and components development.更多还原
