datalog การใช้

• A sufficient condition for tractability is related to expressibility in Datalog.
• Furthermore, Datalog queries on finite sets are guaranteed to cut operator.
• Some widely used database systems include ideas and algorithms developed for Datalog.
• David Maier is credited with coining the term Datalog.
• Unlike in Prolog, statements of a Datalog program can be stated in any order.
• This makes Datalog a truly declarative language.
• Major logic programming language families include Prolog, Answer set programming ( ASP ) and Datalog.
• Other logic programming languages, such as Datalog, are truly declarative but restrict the language.
• In ASP and Datalog, logic programs have only a procedural interpretation as goal-reduction procedures:
• Prolog gave rise to the programming languages concurrent logic programming languages, constraint logic programming languages and datalog.
• KAON2 is implemented by algorithms which reduce a SHIQ ( D ) knowledge base to a disjunctive datalog program.
• Moreover, Datalog engines are behind specialised database systems such as Intellidimension's database for the semantic web.
• By SRI International ( future . sri . com / bip / datalog / didesc / 2096 . html ).
• These extensions have significant impacts on the definition of Datalog's semantics and on the implementation of a corresponding Datalog interpreter.
• These extensions have significant impacts on the definition of Datalog's semantics and on the implementation of a corresponding Datalog interpreter.
• His professional contributions spanned subjects as diverse as Functional dependency, object histories, spreadsheet histories, Datalog, and data restructuring.
• While any conjunctive query can be written as a Datalog rule, not every Datalog program can be written as a conjunctive query.
• While any conjunctive query can be written as a Datalog rule, not every Datalog program can be written as a conjunctive query.
• If we apply the stratification test known from Datalog, the predicate shaves is exposed as unstratifiable since it is defined recursively over its negation.
• In logic programming and datalog, computation and query evaluation are performed by representing the negation of a problem to be solved as a goal clause.
