Paperback. Condición: New. 1st. The use of logic in databases started in the late 1960s. In the early 1970s Codd formalized databases in terms of the relational calculus and the relational algebra. A major influence on the use of logic in databases was the development of the field of logic programming. Logic provides a convenient formalism for studying classical database problems and has the important property of being declarative, that is, it allows one to express what she wants rather than how to get it. For a long time, relational calculus and algebra were considered the relational database languages. However, there are simple operations, such as computing the transitive closure of a graph, which cannot be expressed with these languages. Datalog is a declarative query language for relational databases based on the logic programming paradigm. One of the peculiarities that distinguishes Datalog from query languages like relational algebra and calculus is recursion, which gives Datalog the capability to express queries like computing a graph transitive closure. Recent years have witnessed a revival of interest in Datalog in a variety of emerging application domains such as data integration, information extraction, networking, program analysis, security, cloud computing, ontology reasoning, and many others. The aim of this book is to present the basics of Datalog, some of its extensions, and recent applications to different domains.…

Brossura. Condición: new. Modena, 2021; br., pp. 318, cm 15x21. "Una vita da tifoso" è solo un racconto di un ragazzo che ama lo sport, lo ha sempre amato fin da bambino. Per essere presente nello sport ha fatto di tutto, dal calciatore all'allenatore, passando attraverso la travagliata strada dell'esperienza arbitrale che esercita in due diversi momenti della sua vita. Le qualità tecniche da calciatore limitate gli danno la possibilità di diventare però un grande tifoso. Non una vera e propria storia, non una vera e propria autobiografia: uno spaccato della società napoletana dagli anni '70 in poi, un'opera che raccoglie una serie di aneddoti e di leggende metropolitane riguardanti il calcio e altri sport visti dagli occhi di tifoso. Anche la passione sportiva, se non diviene "oppio dei popoli" o veicolo di violenza, può rappresentare una lezione di vita, fonte di civiltà, nido di dolci ricordi. Libro.…
