模型驱动体系结构MDA及xUML规范在其语境中的探讨

Model Driven Architecture and the Discussion of xUML in the Context of MDA

介绍OMG提出的模型驱动体系结构MDA ,它将与实现技术无关的模型和基于特定技术的模型分离 ,并通过模型间的变换 ,使系统能适应技术的发展 ,解决系统在不同中间件平台的集成、互操作性、可移植性等问题 ,提高生产力 ,保证程序质量 .

This paper presents the OMG's Model Driven Architecture.It separates the specification of system functionality from the specification of the implementation of that functionality on a specific technology platform.And it makes the system adapt to evolution of technology by the transformation of models.It addresses to solve the problem of integration, interoperability and portability.So the productivity will be enhanced and the quality will be assured by applying the MDA.Furthermore, we discussed the specification Executable UML(xUML) in the context of MDA.
