摘要 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.
