【摘要】 模型驱动架构(MDA)是对象管理组织(OMG)提出的一种新的软件开发框架。与传统软件开发不同,MDA以模型为中心,使用模型来指导系统的设计、开发和维护。它将模型和实现技术分离,降低了软件开发的难度,提高了软件开发的效率。随着信息技术的发展和社会信息化程度的提高,信息系统的应用种类越来越多,应用环境也越来越复杂,对不同平台之间的互操作能力的要求也越来越高。结合SOA的思想,本文设计实现了面向目标异构平台的MDA系统,它能较好地实现这种复杂应用环境下的系统开发。本文从分析MDA的基本理论入手,研究了MDA中的建模技术和模型转换技术。在此基础上,针对电子政务应用,本文主要研究了以下三方面的内容:首先,本文研究了基于目标操作化的业务建模技术,分析了零码Portal平台中业务目标的PIM模型,并定义了PIM元模型中的基本元素。其次,本文根据电子政务领域的特点提出了基于异构平台的目标应用系统体系结构,给出了面向异构目标平台的PSM组件模型。最后,本文提出了面向异构目标平台的MDA平台的系统框架,给出了该平台中模型转换模块、桥接器模块和应用集成模块的设计与实现,并研究了模型与代码的同步机制。更多还原

【Abstract】 Model Driven Architecture (MDA) is a new software development framework proposed by the Object Management Group (OMG). Different from the traditional software development, MDA is model-centric, using the model to guide system design, development and maintenance. It makes model separated from implementation technology, which reduces the difficulty of software development and improves the efficiency of software development.With the development of information technology and a higher level of social information, information systems have more and more types of applications, application environments are increasingly complex, and between the different platforms, interoperability requirements are getting higher and higher. Combination of the SOA thought, this paper designs and implements a system of heterogeneous target platform oriented MDA, which can better achieve development of application systems in this complex environment.This paper analyzes the basic theory of MDA as beginning and further studies the modeling and model conversion technologies in MDA. On this basis, for e-government applications, this paper researches the content of following three aspects:First of all, this paper studies the goal operationalization based business modeling techniques, analyzes the PIM of business objectivesin the zero-code Portal platform, and defines the basic elements in the PIM meta-model elements. Secondly, according to the characteristics of the field of e-government, this paper proposes a based on heterogeneous platforms target application system architecture, and analyzes the PSM component model for heterogeneous target platform.Finally, this paper presents a system framework of heterogeneous target platform-oriented MDA. And then, this paper designed and implemented the model conversion module, bridge module, application integration module of the platform and analyzed the mechanism of model and code synchronization.更多还原
