摘要

与关系数据库模式一样，由于元素和属性之间存在一些异常的功能依赖关系，XML数据集可能包含冗余信息。本文提出了一种基于约束树模型的XML功能依赖的新概念。提出了一种消除XML数据集中数据冗余的算法，该算法将上述新的XML功能依赖关系和数据集本身结合在一起。

Removing XML Data Redundancies by Constraint-Tree-Based Functional Dependencies

XML datasets may contain redundant information due to some anomaly functional dependencies among elements and attributes just as those in relational database schema. This paper proposes a new concept of XML functional dependency based on constraint-tree model. An algorithm is given to remove data redundancies in XML datasets, in which the above new XML functional dependency and dataset itself are together applied.
