摘要: 对海量XML文档的索引查询技术进行研究,提出一种XML数据分页索引查询实现方法。该方法把页面元素标记数量作为数据分页依据,建立XML数据的分页索引,并在该分页索引上实现XPath查询。实验结果表明,该方法能够针对不同的索引页面,采用不同的索引查询方法,有效地提高了查询效率。

关键词: XML数据, 索引, 查询, 页序

Abstract: The indexing inquiry technology of massive XML document is researched, and an XML data pagination index inquiry method is proposed, which makes the number of elements in a page as the basis for data pagination, and creates XML data pagination index. The XPath inquiry is implemented on this pagination index. Experimental results show this method can use different index inquiry ways according to different index pages, and promotes the efficiency of inquiry.

Key words: XML data, index, inquiry, page order
