Abstract
With the enormous amount of data stored in the World Wide Web, it is increasingly important to design and develop powerful web warehousing
tools. The key objective of our web warehousing project, called WHOWEDA (Warehouse of Web Data), is to design and implement a web
warehouse that materializes and manages useful information from the Web.
In this paper, we introduce the concept of Pi-web join in the context of WHOWEDA. Pi-web join operator is a web information manipulation
operator to combine relevant web information residing in two web tables. Informally, it is the combination of web join and web project operators
which filter out irrelevant information from a joined web table. In this paper, we show how to construct the Pi-joined web table and its schema.
We also highlight the benefits of the Pi-web join operator.
