Datalog Revival and Limitation of Relational Calculus

Datalog, a logic-based programming language, saw a revival in the 21st century with the addition of recursion to positive first-order queries. The history of Datalog traces back to the 1970s with the idea of adding recursion to FO queries. Despite the industry's initial lack of interest, Datalog fou
