基于MDA的快速软件开发框架的研究

摘要

通过研究基于MDA的软件开发理念,分析和探讨了软件开发效率、系统移植、互操作性以及软件维护等突出问题.提出了一种软件开发框架,采用XML建立平台无关模型(PIM),建立模型驱动运行时环境(MDR),对PIM模型进行解析和执行,最终生成HTML页面.框架能够极大地提高开发效率,方便系统扩展和后期维护,有利于开发人员进行Web应用程序的二次开发.%This paper proposes a software development framework based on the concept of MDA to resolve the problems of current software development process such as software development effciency ,system migration,interoperability, and software maintenance,etc.PIM ( platform - independent model ) first established by the XML in this frameworke The HTML pages were produced after the establishment of the PIM model analysis and implementation by MDR ( model- driven runtime environment).This software development framework greatly improves the sofrware development in effciency,expansion and maintenance of Web system, Ans it is also more conductive to Web developers to the secondary, development of Web applications.
