Programming as theorem-proving — state facts and rules, ask questions, let unification do the walking. The heart of the logic-programming lineage.

Colmerauer and Roussel's Prolog (1972) — logic programming's first and only mainstream success — made the program a set of Horn clauses and the execution a theorem proof.\n\nIt was Japan's Fifth Generation project language and remains the standard for logic programming; Datalog is its database descendant.
