【摘要】 在比较现有的区间编码方式和XML索引技术的基础上,提出一种基于Schema的XML索引技术DSBXI(Dynamic Schema-Based XML Indexing)。DSBXI充分利用XML Schema建立XML索引,同时在查询过程中线索化查询信息,使相同路径查询无需进行结构连接运算,提高查询效率。更多还原

【Abstract】 Comparing the current region encoding with XML indexing technique,it was proposed a kind of XML indexing based on XML Schema DSBXI(Dynamic Schema-Based XML Indexing).DSBXI was made the most use of the XML Schema to build the XML indexing,at the same time,thread the querying information.The structural join operation wasn?t needed for the same path querying.The efficiency of path querying was improved.更多还原
