In this paper; we describe a data warehousing system that materializes and manages useful information from the web in order to support better data analysis and manipulation by the users using WWW as a global digital library. Unlike the conventional web search engines, the proposed web warehousing system is designed based on an advanced web data model together with a set of powerful web operations. The web table constructs in the proposed web data mode2 capture both the content and link infonnation of web pages extracted from WWU! This paper gives an overview of the web warehousing system and demonstrates its usefulness using a set of examples.
