Pushing Database Changes to the Web with Datomic

Lately I’ve been playing around with Datomic, a database invented by Rich Hickey, the creator of Clojure. Datomic feels like a natural extension of Clojure’s immutable, persistent datastructures. From Datomic’s architecture documentation:

A Datomic database stores a collection of facts. The facts in a database are immutable; once stored, they do not change. However, old facts can be superseded by new facts over time. The state of the database is a value defined by the set of facts in effect at a given moment in time.

Daniel Higginbotham wrote a great tutorial on the basics of Datomic called Datomic for Five Year Olds, continue.
