UML模型到N层Web模型的模型驱动转换

Model driven transformation from UML model to the N-layer Web model

模型驱动架构(MDA)是由对象管理组织(OMG)提出的应用模型技术进行软件开发的方法和标准体系,其核心理念是平台无关模型建模和平台特定模型转换。通过编程实现基于元对象机制2.0(MOF2.0)查询/视图/转换(QVT)标准定义开发的框架,该框架可以将元模型转换为特定N层应用程序类,实现主要程序功能,从而大大提高开发效率。验证了通过编程实现模型驱动转换的灵活性和功能实现的多样性,包括XML文件对模型规范的描述以及生成代码的完整性。

Model Driven Architecture （MDA） refers to the method and standard system for the application of model technology in software development proposed by Object Management Group （OMG）,the core idea of which includes the modeling of platform-independent model and the transformation of plafform-specific model.The framework was realized by programming based on Meta Object Facility 2.0 （MOF2.0） Query/View/Transformation （QVT） standard definition,and it could achieve transformation of meta model to specific N-layer application class and realize main functions of the program,thus greatly improving the development efficiency.The flexibility of model-driven transformation and diversity of function realization achieved by programming were verified,including the description of model specification by XML documents and the integrity of code generation
