Mapping composition is a fundamental operation in metadata driven applications. Given a mapping over schemas �1 and �2 and a mapping over schemas �2 and �3, the composition problem is to compute an equivalent mapping over �1 and �3. We describe a new composition algorithm that targets practical applications. It incorporates view unfolding...More
