Parsed tree model of XML document based on relation table
利用关系表构建XML文档解析的树模型

Although the tree could reflect the hierarchical structure of XML document during its data paring and query operations, the efficiency of its data query is low. Based on the fact that the relation-table is a suitable data structure with a large amount of data storage, good query efficiency and operating function, a data model including the relationship table and the tree for storing XML documents is proposed. During its analytical process, the analysis time and the storage space could be reduced by event-based callback sub-analytic method. Thus, the new data model not only can remain the structure of XML document, but also enhance the query efficiency and operation convenience. The results of the XML document parsing and operation experiments with large amount of data show that the data model is especially suit for dealing with large XML documents.
