【摘要】 信息化是高效管理的必由之路，许多机构（政府，企业等）经过近几年的信息化建设，已经初步具备了信息化的软硬件设施，在这些信息化过程当中，管理信息系统起着非常重要的作用，许多机构对自身的管理信息系统建设已经积累了一些经验。但随着IT领域内各种技术的发展，以及机构原有的信息系统众多潜在问题的暴露和机构需求变化的日益增长，许多机构对信息系统提出了更高的要求。另一方面，随着互联网以及软硬件技术的不断发展，分布式，可操作性，异构性已经成为各种计算环境的显著特征，如何创建一个全新的高扩展性的信息系统的问题已越来越引起研究人员和开发人员的关注。本文在分析了传统管理信息系统模型不足和目前机构信息化（特别是电子政务）发展趋势的同时，结合一些开发实例，提出了一种基于XML的管理信息系统结构模型，详细阐述了该模型的横向和纵向视图及工作原理，并重点研究了开发基于XML的管理信息系统过程中会遇到的几个重要问题。比如，在关系数据库中如何实现XML数据的有效存储是当前研究的热点，针对这个问题，本文在形式化XML模式和关系模式的基础上，提出并实现了一种XML Schema到关系模式的转换方法。另外，本文研究的重点还包括XML数据表达，XML与松散耦合等问题。更多还原

【Abstract】 Informatization is the only way to high performance management, Via many years Informatization process., many organizations(governments, Enterprises etc.) have been provided with good soft hardware conditions. No doubt, Management Information System is acting a very important role in the process. Some organizations have accumulated lots of experience. But the performance of Management Information System should have higher standard because the increase of the organization’s demands and the defects that traditional Management Information System have exposed. On the other hand, with the rapid development of Internet and soft hardware technique, all kinds of computing environments nowadays are becoming characterized distinctly by distribution, cooperation, and heterogeneity. Especially, How to design a high flexible Information System becomes a focus of research.Under the analysis of the deficiency of traditional Information System model and the tendency of Informatization (especially E-Government), According to some practical projects, the paper layouts an XML-based Management Information System model. And explains the horizontal and vertical orientation framework and mechanism of this model in particular. At the same time, this paper studies some problems that may emerge when implementing the model. For example, how to persist XML data by RDBMS effectively is a focus of this paper, After formalizing XML Schema and relational schema, we present a algorithm of transforming XML Schema into relational schema and realize the algorithm with Microsoft DOM API and C# language. In addition, expressing data by XML, XML and loosely coupled system are also my emphases.更多还原
