Final Summary
Datalog is a powerful logic language built on facts, rules, and recursion.
Ideal for databases, compilers, graph reasoning, and policy engines.
Predictable execution and strong mathematical grounding make it essential in many advanced systems.
A foundational language in static analysis, authorization, and knowledge reasoning.
Faq
Is Datalog still used?
Yes - heavily used in static analysis and modern policy systems.
Is Datalog Turing-complete?
Standard Datalog is not, by design, for predictability and termination.
How does it differ from Prolog?
No backtracking, no complex terms, purely declarative.
Where is it used today?
Compilers, security engines, graph analysis, and datastores like Datomic.
