In this talk, Rich Hickey from Datomic, gives an introductory talk on Datomic as a functional database. He talks on a Datomic as value Database, which means that you can write functions that take values as arguments and similarly can return a database value as its result. He also talks on the importance of a durable, consistent Database that can be shared across processes.  Rich also offers some hands on use from Clojure. This talk was recorded at the LispNYC meetup at Meetup HQ.
