Study of extending Huffman code-based XML storage and query

This article promises a method of XML document storing and querying, and improves storing and querying of the XML documents effectively, and avoids multi-level complex XML data conversion in processing XML data. Taking full advantage of relational database technology, this article effectively realizes the massive data storage and query. Analytical techniques used XML SAX, and the expansion of existing Huffman coding, storages node information and the relationship between nodes with extending Huffman Code. Traversing through the corresponding expansion of XML document, this method generates XML extending Huffman code. The method of extending Huffman code-based XML storage and query implements the storing and querying of node information and the information between nodes. There is no doubt that this method is feasible in practical use.
