Datomic is a new database that models the world as a series of immutable facts. This approach to modeling the world allows you to finally ask the question "what is the value of my database right now? and what was it a week ago?" If your database has a concrete value, you can store the database locally in your app and query against all values throughout time. Datomic puts forth many interesting ideas such as this, and provides new ways to think about testing, data storage, and querying. This talk will touch on all the big ideas behind Datomic and go hands on with a live Datomic code base to show how these big ideas translate into a compelling model of how to architect data systems in 2014


The Navy League Building Conference Center is what some people call the room. The building closes at 6 PM, but we’ll hang out there to let everyone in on the Wilson Blvd entrance. Call Wes @ 540 449 5828 if you get stuck outside.

Parking is not free in the building ~$8 for the night. Street parking opens up at 6PM, if you can find a spot. Parking is available on Adams Street on the west side of the building. Left turn around the building from Wilson, or left turn in front of the building from Clarendon.

Courthouse Metro is very easy [if you know the trick!]. At metro, go up the escalator and through a turnstile, and make an immediate right turn to the elevator. Take the elevator to the street, and as you exit the elevator, cross the street in front of you (Clarendon), go left to get on Wayne Street, and walk a short block to Wilson. Turn left around the bank and enter 2300 Wilson Blvd (Navy League Building). If you miss the elevator, you have to walk about 3 blocks twice, once underground and once on the street.

Looking forward to it! Thanks again to Segue Technologies for providing the meeting space, and to Neo Technology for beer and pizza.
