Translating XML to Normal Relational Schema Based on XML Key
基于键的XML模式到关系模式的规范化转换

This paper proposes a Normalized Translation Algorithm for translating XML to relational schema based on XML key, which tackles the redundancy and un-standard expression in the translation. According to a group of deduce rules about XML functional dependency, we expand the FD-Set to avoid losing semantics of original XML. Then we use a group of clear rules to clear up the redundant FD and enable the final FD-Set is minimum. Finally, we take the XML keys as the center to divide the relation attributes, obtain the relation table, and guarantee the relation schema satisfies 3NF.
