The Nested Interpolation Based Grid File,a new structure for physically organizing a set of multidimensional points. This structure called the Nested Interpolation-Based Grid File (NIBGF) represents a synthesis and an improvement of results obtained in Interpolation-Based Grid Files (IBGF), BANG files, and K-D-B-trees. The data search spac

Complexity of recursive production rules execution,nt an approach based on graph modelling. We show on some elementary recursive rules the power of this method. We assume a realistic probabilistic model, i.e. the data distributions of the relations involved may be dependent and non-uniform. Under smooth hypotheses, we introduce a notion of “maximum

Monadic databases with equality,t domain elements are represented by unary predicate symbols and not as constant symbols. We provide a formal system for ME-databases and we prove its soundness and completeness. We give also polynomial algorithms for evaluating elementary queries corresponding to the implication problem on ME-databases.
