【摘要】 针对由业务模型直接定义XML Schema存在较多的困难，提出了一种把UML技术用于XML Schema建模的方法。该方法通过领域建模定义了3层模型，即概念层模型、逻辑层模型和实现层模型，分别对应于业务模型的分析、设计及实现阶段，并对各层模型之间的转换方法进行了有效的探讨。更多还原

【Abstract】 As there are some difficulties in defining XML Schema according to business model directly, this paper presents a method to apply UML to XML Schema modeling. This method defines three levels of model by domain modeling. These three levels are conceptual level, logical level and physical level. They correspond to the analysis, design, and implementation of the business model individually. And this paper discusses the mapping method between models of different levels effectively.更多还原
