Logic programming delivers great expressive power: you work in domain abstractions, and your program figures out execution details. And it has never been easier. With the Datalog engine in Datomic Free, you can work both with databases and with your own data in plain Java collections.
Datalog queries have the expressive power of SQL + recursion, so is a good fit for systems that want “the power of SQL” but e.g. more flexibility. When combined with a universal schema, Datalog is particularly easy to learn and to read.
Datomic's datalog implementation works with immutable database values, providing additional benefits:
