On the Views for Semistructured Data
基于XML的半结构数据的视图问题研究

In this paper we introduce the view specification language and consider the problem of answering queries posed on semistructured data views. The two main approaches,query rewriting and view materialization,are outlined. We also discuss the views and its maintenance for XML data. Based on the above discussion a view architecture for integrating data from heterogeneous source or from the WWW is proposed.
