Urn Models and Yao’s Formulathat such situations can be modelized by probabilistic urn models. This allows us to fully characterize the distribution probability of the number of selected blocks under uniformity assumptions, and to consider extensions to non-uniform block probabilities. We also obtain a computationnally effcient approximation of Yao’s formula.

Advances in Immigrant Family Researchnjunctive queries and embedded dependencies, as well as many interesting examples of complex value and oodb queries and integrity constraints. We show that some important classical results on containment, dependency implication, and chasing extend and generalize to this class.
