XML数据存储研究

Research on the Storing Strategy of XML

网络上正在产生的大量的数据主要是HTML格式的数据,可以预计将来的网络上还将产生大量的数据,不过越来越多的将是XML格式。如何有效地存储和检索网络上的XML数据成为一个研究热点。由于数据库技术不断趋于成熟,一种方法是采用数据库对XML数据进行存储和查询等操作。其基本思想就是利用XML数据模式到数据库的数据模式的映射来存储。另外也可以采用文件形式来存储;还可以采用半结构化数据库存储或者采用面向对象数据库存储。

There are plenty of data on Web now, most of them are of HTML format. And it is sure that more and more data appear will on Web, but most of them will be of XML format. How to store and query XML data efficiently is becoming urgent. Because the database technologies are highly developed, it＇ s natural to store XML data in databases. And the basic principle is to process the storage by mapping the XML data mode into the database data mode. Of course it can be stored in file or semi - structured databases , or object - oriented databases too.
