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.
