【摘要】 随着我国社会信息化进程的不断加快，企业也不断加快信息化建设的步伐，以满足客户对产品的差异化和个性化需求，适应不断变化的企业外部环境，达到提高企业核心竞争力的目的。然而随着企业信息化建设过程的深入，企业开始面临着信息膨胀、信息孤岛、信息混乱等新问题。因此，企业现在迫切需要引进一套新的信息组织和管理的指导思想和实用工具来解决这样一些问题。企业信息构建(EIA，Enterprise Information Architecture)作为信息组织和管理的一种新理念和方法近年来在企业信息化研究领域展开了大量的讨论，它被越来越多的人看作是解决企业信息化新问题的有效方法。本文从EIA理论的渊源出发，研究了EIA理论的发展过程，对当前EIA框架理论与建模方法进行了总结分析。然后在相关研究的基础，提出了基于领域工程和信息重用的企业信息构建框架，同时阐述了该框架中的各个主要模型。为了保障企业信息框架的整体一致性，本文分析总结了上述模型的相关建模方法，提出可以利用日益强大的UML进行统一建模，以解决企业信息构建框架中出现各模型不一致性的矛盾。对于该框架中目前缺乏基于UML建模方法的系统高层信息模型，针对其采用的是WIED模型，本文利用UML提供的扩展机制，设计了一个UML Profile对WIED模型进行了改进，使之能与UML进行转换，从而间接地保证了建模的统一性。最后，根据以上对企业信息构建框架及其建模的研究总结，对企业信息构建框架的改进、建模技术的研究以及实现模型自动转换等方面进行了展望。更多还原

【Abstract】 With our information-based society in the process of speeding up, the pace of enterprise informationization construction also has been quickened to meet the customer’s demands of product differentiation and individuation, to adapt to changing external environment, for the purpose of improving enterprise’s core competitiveness. But with the in-depth process of enterprise informationization, enterprises started facing new problems such as swelling information, isolated islands of information and information chaos. Therefore, there is an urgent need for enterprises to introduce a new guiding ideology and practical tool for information management to solve such problems.As a new guiding ideology and method for information management, Enterprise Information Architecture (EIA) have arose a great deal of discussions in enterprise informationization research field. And more and more people consider it as an effective way to solve new problems of enterprise informationization.The paper introduces the development of the EIA theories, then analyzes and sum up the current theories and methods of EIA framework and its modeling. Then in the relevant research base, we design an EIA framework based on domain engineering and information reuse, and also explain primary models in the framework. To ensure the overall consistency of EIA, the paper summarizes the analysis of the above modeling methods then suggest that we can settle the inconsistency contradictions of models in the EIA framework by making use of the increasingly powerful UML. As for system high-level information model in the framework, which is modeling by WIED but not UML-based method, the paper designs a UML Profile for WIED model based on the UML extension mechanism so that it can support the transformation between WIED and UML, thus indirectly ensured the consistency of modeling. Finally, on the basis of the above research on EIA framework and its modeling, we discuss the further work on the improvement of the EIA framework, modeling methods and automatic model conversion.更多还原
