Incomplete Information and Dependencies in Relational Databases
Summary: Incomplete-information relational databases mix null-valued data with dependencies; chase converts dependencies into a null-based form. With arbitrary implicational dependencies, the transformation is not fully equivalent, and info corruption evades detection under projection, positive selection, union, join, and renaming; also studies view-dependency effects.
