中文摘要：

分析了传统的软件系统开发方法如使用工具和模型框架等适合于建立单个的面向对象或基于组件开发的软件,以及不适合于开发具有柔韧性的分布式企业应用系统的不足之处,针对近几年提出的面向服务的体系构架SOA（Service Oriented Architecture）方法只适合于一些特殊领域的问题,提出了应用模型驱动的开发方法来解决SOA中复杂分布式系统的建模与设计问题,利用模型驱动体系构架MDA（Model Driven Architecture）中平台无关模型（PIM）的特点建立模型,并通过MDA工具自动转换到基于SOA的平台相关模型（PSM）,如Web服务,Jini等平台,从而实现了SOA的简单性、高效性和广泛的应用性。

英文摘要：

This paper presents the deficiencies of the traditional approaches to software systems development,such as by using tools and model frameworks for building individual object-oriented or component-based software,and they are not suitable for designing flexible distributed enterprise systems.In recent years,the service-oriented architecture（SOA） has been proposed as a suitable architecture for development of these systems,and however,it is applicable to specific domains only.Therefore,this paper proposes a model-driven approach to SOA model and design of complex distributed systems.By using the PIM feature of MDA to design models,and then transforming PIM into the PSM based on SOA by some MDA tools,such as Web services,Jini or other platforms,an easy efficient and extensive application of SOA is realized.
