RESEARCH ON QUERY TECHNOLOGY OF XML DATABASE

摘要

As a standard of describing the scheme information or structure information of XML document, XML Schema plays an important role in the building of XML indexing and improving of the query efficiency. Now most of the XML indexing structures focus on studying the structural query. Comparing the current region encoding and XML indexing technique, the paper brought forward a kind of XML indexing based on XML Schema SBXI (Schema-Based XML Indexing). SBXI made the most of the XML Schema to build the XML indexing to improve the efficiency of path querying and prospected the future research directions.
