Nested Dependencies: Structure and Reasoning
Summary: Systematic investigation of nested GLAV mappings (nested tgds) for data exchange, focusing on reasoning, algorithms, and structural properties. Key results: decidability of the implication problem for nested tgds, structural analysis of cores, techniques separating nested from SO tgds, and a decidable test whether a nested GLAV mapping is equivalent to a (non-nested) GLAV mapping.
