Abstract

We consider the problem of rewriting queries based exclusively on views. Both queries and views can contain aggregate functions and include arithmetic comparisons. To study the equivalence of a query with its rewriting query, the so called ”linearizations of a query” need to be computed. To find the linearizations of a query, the linearizations of terms from the query need to be generated. We propose an algorithm to find these term linearizations and give a bound for its time-complexity.
