Datomic is a distributed database and implementation of Datalog.[3][4] It has ACID transactions, joins, and a logical query language, Datalog.[5][6] A distinguishing feature of Datomic is that time is a basic feature of data entities.[7]

Architecture

It has been designed for first-class use with JVM languages such as Java and Clojure.[8]

In its reference architecture, Datomic uses peers[9] and transactors[10] which run on the JVM.
