Datomic is a distributed database and implementation of Datalog.[1][2] It has ACID transactions, joins, and a logical query language, Datalog.[3][4] A distinguishing feature of Datomic is that time is a basic feature of data entities.[5]

Architecture

It has been designed for first-class use with JVM languages such as Java and Clojure.[6]

In its reference architecture, Datomic uses peers[7] and transactors[8] which run on the JVM.
