To be reasonable, for an honest "no" to this question, most of your data should be document-like storage of semi-structured nature.
但是准确地说，如果要对这个问题回答 “不需要”，那么您的大多数数据应该是半结构化的文档。
Representing semi-structured data as an XML-based document requires a robust data-mining system to support XML consumption, manipulation, and output.
将半结构化数据表示为基于 XML 的文档需要一个健壮的数据挖掘系统来支持 XML 消费、操纵和输出。
