Jie Ying, Suyan Cao, Yuan Long · 2012
Due to self-defined labels and flexible structure, XML has a great advantage of storing data over the Internet. Thereby, how to effectively map XML documents to relational database which is mainstream database in the different domain becomes a hot topic for current researchers. This paper proposed a new storage strategy based on the modified tree model. Our approach has three pre-defined tables to store the main structural information within the tree structure respectively. By labeling nodes with specific information of parent id and position, the relationship of nodes such as ancestors and parents can be kept to support the query and reconstruction of the XML Document.
