The main goal of optimization is to perform query computations using data available locally and data that can be quickly transferred to a central site from t

Such trade-offs are already made in existing application systems — particularly in real-time databases where timeliness is more important than exactness. We consider other ways in which correctness may be relaxed in favour of performance. Specifically, we consider

After illustrating what we call standard transformation into F-logic, we investigate how the resulting object-oriented database schema can be improved by utilizing certain semantic constraint

In addition to a certain sequence of object names and values of object characteristics, the OOML specifies a scheme of relations between the objects..We show that the object relations scheme may be treated as a specification of the mapping from

Study of CPP Mechanisms by Mass Spectrometryhe language Plop as a minimal language for studying polymorphism in a logical database programming language by means of parameterization of predicates. The main idea is to introduce generic predicates which have two lists of parameters. While the second list contains the usual arguments, the first l

Study of CPP Mechanisms by Mass Spectrometryare a number of formalizations of this in the literature. However, the naive formalization is false: As shown by Ross, SLD-resolution can be much more efficient than bottom-up evaluation with magic sets on tail-recursive programs..We show that this happens . for tail-recursive programs, and that the

The most outstanding characteristics of GRADE are that the tool is based on a unified specification language GRAPES and that it supports all information system development phases including analysis, requirements specification, design and implementation.
