On Lossless Transformation of Database Schemes Not Necessarily Satisfying Universal Instance Assumption (preliminary version)
Summary: Lossless transformation for multirelational schemes without the universal-relation assumption; two notions (CWA, OWA), OWA more tractable. Algorithm to test losslessness and synthesize inverse mappings for mappings built from projection, product, restriction; handles broad dependency classes and characterizes inclusion dependencies with the finite-chase property.
