Most of the research work on deductive databases has concerned the Datalog language, a query language based on the logic programming paradigm which was designed and intensively studied for about a decade. Its origins date back to the beginning of logic programming, but it became prominent as a separate area around 1978, when Hervé Gallaire and Jack Minker organized a workshop on logic and databases.

Abstract
Most of the research work on deductive databases has concerned the Datalog language, a query language based on the logic programming paradigm which was designed and intensively studied for about a decade. Its origins date back to the beginning of logic programming, but it became prominent as a separate area around 1978, when Hervé Gallaire and Jack Minker organized a workshop on logic and databases. In this entry, the definition of the typical computation styles of Datalog will be given, the most important optimization types will be summarized, and some developments will be outlined.File in questo prodotto:
