Base de données déductive - Deductive database Un article de Wikipédia, l'encyclopédie libre Une base de données déductive est un système de base de données qui peut effectuer des déductions (c'est-à-dire conclure des faits supplémentaires) sur la base de règles et de faits stockés dans la base de données (déductive). The query language of PHI is Datalog and its query processing is performed in a bottom-up manner. This paper presents an approach for integrating deductive databases.

It helps to combine the RDBMS with logic programming. . Forexample, the RDBMS that provide recursive SQL have based their implementations ondeductive database standards.A more viable approach is to use a regular relational database with an added Datalog layer forlogic programming. Query optimization of PHI is the combination of query transformation and techniques developed for relational databases. PHI is composed of two layers which handle intensional and extensional databases, respectively. Skip to main content.sg. Use a declarative language (such as prolog) to specify those rules and facts.

Datalog: Deductive Database Programming. • Deductive databases combine logic programming with relational databases to construct systems that support a powerful formalism and are still fast and able to deal with very large datasets. A deductive database is a database system that can make deductions (i.e., conclude additional facts) based on rules and facts stored in the (deductive) database. What can you do with them? - What are knowledge-based systems? Use an inference engine which can deduce new facts and rules from those given. While these operators allow the simple expression of many database programs, it is possible to write simple programs with a complicated semantics (as in the case for negations), and so many of the concepts introduced for negation (e.g., stratification) are also used for aggregate operators.
