摘要
从消除XML DTD文档内数据冗余的角度出发研究了文档的规范化问题,首先引入XML DTD上路径和函数依赖的定义,并提出定义XML上的数据冗余;其次基于函数依赖,提出了规范化的DTD概念和XML DTD规范化处理规则;最后给出了一个将XML DTD转化为规范化的处理算法。
The normalization problem of XML DTD is studied, as viewed from avoidance of redundant information in documents. First, the paper gives the definition of functndional dependencies and path for XML DTD and the concepts of reduancy is provided. Second, based on the functional dependency, the concept of normalized DTD and normalization rules for XMI. schema are provided. I.ast, an algorithm for converting XML DTD into a corresponding normalized one is provided.
