摘 要: | XML之所以在很短的时间内就获得广泛认同,成为一种被大量使用的通用的数据格式,是因为XML文档很容易表达来自不同源的数据,是实现数据集成和交换的重要方法。但是其所能表示的语义信息却相对有限。在已有的DTD和XMLschema规范的基础上进一步增强定义完整性约束的能力,对此进行了论述。

Abstract: | Because XML document can easily express the data from the different sources, and it is a important way to achieve data integration and exchange, XML has been widely recognized and used as a common data format in a short time. But the semantic information which XML express is relatively limited. The major work of this paper is to enhance the ability of defining integrity constraint based on the existing DTD and xml schema. |
