The Design and Development of a New Storage Mode Supported Dynamic XML Documents

For the problem that XRel model can not effectively support the storage of dynamic XML document, the following improvements and extensions were made in this paper. First, a new encoding scheme called NewDietz, which supported the storage of dynamic XML document, were proposed based on the Dietz encoding. Second, the relationships logic model which can storage NewDietz coding node was designed, not only ensuring the effective storage of the new node, but also taking into account the problem that the relationship of nodes between ancestors and descendants must be judged firstly when the dynamic XML document restructured in this pattern. At last, a concrete example was given to verify the effect of the practical application of new model.
