The LogicBlox system is a commercial, declarative, incremental logic programming language and deductive database inspired by Datalog. The LogiQL programming language extends Datalog with several features, including stratified negation, aggregation, and a module system. LogicBlox has been used to build pointer analyses for Java.[1]
On December 3, 2014 Predictix acquired LogicBlox.[2] On June 28, 2016 Infor acquires Predictix.[3]
