Translating XML to Normal Relational Schema Based on XML Key
Wang Mei · 2007
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.
