一种模型驱动的Web应用系统开发方法

为解决模型驱动开发过程中高层模型描述和模型转换方面存在的问题,以软件体系结构为基础,通过对UML进行扩展,提出了一种平台无关的Web应用建模方法,包括体系结构模型、逻辑视图、静态视图和界面展示视图四部分。然后基于源模型语义特征在目标语义域中的重新构造,依据转换两端建模元素的语法结构和语义表达特性定义模型间的映射规则,实现模型转换和目标代码生成。以J2EE作为目标平台进行实验验证,表明此方法保持了高层模型的平台无关特性,能够对模型驱动的软件开发提供有力的支持。

A Model-driven Development Approach for Web Application Systems

Focusing on the development for Web application systems,a platform independent modeling approach is presented to resolve the problems in describing high level models and model transformation of model-driven develop- ment.This approach is based on software architecture and extended UML,which comprises architecture model, logic view,static view and UI presentation view.Then,based on the idea of elements in source semantic domain being reconstructed in the target semantic domain,mapping relations from the source model to the target are built according to the syntactic structure and semantic features of both metamodels,and thus to realize model transforma- tion as well as target code generation.J2EE was used as a target platform in the experiment which showed that this annroach can support model driven software engineering effectively for keeping independency for high level models.
