Existence of huge amounts of data on the Web has developed an

undeferring need to locate right information at right time, as well as

to integrating information effectively to provide a comprehensive

source of relevant information. There is a need to develop efficient tools for analyzing and managing

Web data, and efficiently managing Web information from the database

perspective. The book proposes a data model called WHOM (Warehouse

Object Model) to represent HTML and XML documents in the warehouse. It

defines a set of web algebraic operators for building new web tables

by extracting relevant data from the Web, as well as generating new

tables from existing ones. These algebraic operators are used for

change detection.
