摘要： 对大部分XML数据的索引结构,由于元素间的相互关系,数据内容更新会引起XML元素域表示值的大量变动,当XML数据内容频繁改动时就成为严重问题。该文提出了一种称为BRRC的有效方法以减少XML数据更新时引起的元素域表示值的更改数量。

Abstract: For most index structures of XML data, due to the relationship among elements in XML documents, the updating of source data will result frequently values changing of XML elements, which causes a serious problem. This paper proposes an efficient method called BRRC to reduce the total quantity of elements whose coordinate expressing value must be changed when a content of source data updating occurred.
