中文摘要：

传统软件开发模式由于其最终生成产品是程序代码，难以适应需求的快速变化，软件开发过程中不可避免地出现非标准化与非自动化的问题。为了解决上述问题，在介绍MDA开发过程的基础上，探讨了平台无关模型和平台相关模型的定义、映射和转化等，并将MDA开发方法和传统软件开发方法进行了分析比较。以决策支持系统为例，描述通过MDA进行软件开发的过程。结果显示，基于MDA的软件开发方法能够由软件模型指导自动生成软件成品，降低了系统的开发成本与设计效率。

英文摘要：

Because the final product generated by traditional software development mode is the program code,it is difficultto adapt to the rapid change of the demand,and the nonstandardization and nonautomation problems are inevitable in the process of software development.In order to solve these problems,the MDA development process is introduced,the definition,mapping and transformation of the platform independent model and platform dependent model are discussed,and the MDA development method and traditional software development methods are analyzed and compared.Taking the decision support system asan example,the process of software development based on MDA is described.The analysis results show that the software development method based on MDA can automatically generate the finished software products by means of software model,which canreduce the development cost and improve design efficiency of the system.
