XML已经成为在Web上表示、交换和集成数据的标准。为了保证XML文档的质量，设计高质量的XML模式变得至关重要。在本文中，我们研究这个问题，设计质量的XML模式，从给定的E-R图。我们首先讨论设计一个好的XML模式的几个标准。根据这些标准，转换规则，然后设计，考虑到所有结构的E-R图。最后，本文提出了一种递归算法，将E-R图转换为相应的XML模式。
XML has emerged as the standard for representing, exchanging and integrating data on the Web. To guarantee the quality of XML documents, the design of quality XML Schemas becomes essentially important. In this paper, we look into this problem by designing quality XML Schemas from given E-R diagrams. We first discuss several criteria in designing a good XML Schema. Following these criteria, transformation rules are then devised that take all constructs of an E-R diagram into account. Finally, a recursive algorithm is developed to transform an E-R diagram to a corresponding quality XML Schema.
