Decomposition of Relational Schemata into Components Defined by Both Projection and Restriction
Summary: Algebraic framework decomposing schemas via projection and restriction (vertical+horizontal), using a Boolean algebra of types and nulls to realize restrictions and projection independence. Defines two-dimensional join dependencies, generalizes acyclicity results, and classifies decomposition dependencies as bidimensional (triple-generating) or splitting.
