Prolog is -
Prolog has its roots in first-order logic, a formal logic, and unlike many other programming languages, Prolog is intended primarily as a declarative programming language: the program logic is expressed in terms of relations, represented as facts and rules. A computation is initiated by running a query over these relations.[4]
The language was first conceived by Alain Colmerauer and his group in Marseille, France, in the early 1970s and the first Prolog system was developed in 1972 by Colmerauer with Philippe Roussel.[5][6]
Prolog was one of the first logic programming languages,[7] and remains the most popular among such languages today, with several free and commercial implementations available. The language has been used for theorem proving,[8] expert systems,[9] term rewriting,[10] type systems,[11] and automated planning,[12] as well as its original intended field of use, natural language processing.[13][14] Modern Prolog environments support the creation of graphical user interfaces, as well as administrative and networked applications.
Prolog is well-suited for specific tasks that benefit from rule-based logical queries such as searching databases, voice control systems, and filling templates.
