模型驱动的软件开发模式研究

文中详细论述了模型驱动的软件开发模式。阐述了以代码为中心的传统软件开发模式的缺点，并通过对模型驱动架构（MDA）涔系结构的讨论．分析出模型各个层次描述语言的要求。分别讨论了MDA软件开发生命周期、MDA软件开发参与者及活动的变更和MDA开发工具的更新，并对MDA软件开发模式进行了评价。在模型驱动的软件开发模式下，软件开发生命周期是由软件系统建模行为驱动的．其开发过程围绕模型的创建和变换开展，其最终目的就是要通过架构性的分离来实现软件开发的轻便性、互操作性和可重用性.

Study on Model Driven Pattern of Software Development

The software development pattern driven by model has been discussed in detail in this paper.The shortcomings of traditional software developing pattern central on codes were presented firstly.The requirements of language for every model level were analyzed via the discussion about model driven architecture.Subsequently,the software developing lifecycle based on MDA,the participants and activities in the MDA process,and the update of MDA developing tools were discussed separately.Meanwhile,the software-developing pattern based on MDA was evaluated.Under the software development pattern driven by model,modeling behavior drove software development lifecycle.Model building and model translating surrounded the development process.The destination of MDA was to achieve the portability,interactivity and reusability of software developing through separating the architecture into many layers.
