XML是因特网中不同企业之间进行信息交流的一种标准的数据转换模式，为了加速数据之间的转换，企业组织通过定义公共数据文档接口来实现基于XML的应用。本文提出了一种新的将关系数据模式转换为XML模式的方法。在转换的过程中，不仅考虑关系模式的结构，而且考虑语义约束，比如内部函数依赖。该方法的输入模式是具有多值函数依赖的关系模式，输出模式是XSchema。最后，通过实验对该转换方法进行了验证。

XML is the standard format for data exchange between interenterprise applications on the Internet. To facilitate data exchange, industry groups define public document type definitions that specify the format of the XML data to be exchanged between their applications. In this paper, we propose a new method to convert the relational data into XML. During the conversion, we consider not only the structure of relational schemas, but also semantic constraints such as inclusion dependencies during the translation, which takes input as a relational schema where multiple tables are interconnected through inclusion dependencies and converts it into an XSchema. Finally, we present the experimental results using real schemas to validate the method.
