Algebraic operations on bags in a web warehouse
International Computer Science Conference, 1999•Springer
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 web union, web intersection, web join and local web
coupling behave in the context of web bags. Our study reveals that the presence of identical
web tuples accentuate the computational efficiency of some of the web algebraic operators.

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. Our study reveals that the presence of identical web tuples accentuate the computational efficiency of some of the web algebraic operators.
