Algebraic operations on bags in a web warehouse

In this paper, we discuss various algebraic operations on web bags in the context of our web warehousing project called WHOWEDA (WareHouse Of WEb DAta). Informally, a web bag is a web table which allows multiple occurrences of identical web tuples. We examine how some of the web operations such as w...

Informally, a web bag is a web table which allows multiple occurrences of identical web tuples. We examine how some of the web operations such as web union, web intersection, web join and local web coupling behave in the context of web bags.
