What is the difference between Datalog and LogiQL?

The LogicBlox database is programmed using the LogiQL language, which is according to their site some sort of variant of Datalog:

Applications are written using the LogiQL language, an extended version of Datalog

What exactly are the differences between Datalog and LogiQL?

Solution

  • LogiQL is indeed a superset of Datalog, adding various features, including:

    • Transaction support
    • An extensional database where facts can be dynamically inserted and removed (i.e. the set of facts is not "static")
    • Entities
    • Aggregations
    • Delta logic to update the extensional database
    • Pulse predicates whose facts are only kept during the lifetime of a transaction
    • Modules, for large-scale application development
    • Support for machine learning and optimization

    There's probably more that I'm forgetting.
