Hands-on Clojure: Introducing Datomic

Datomic is the revolutionary new database from Rich Hickey, the
inventor of Clojure. It is a distributed database designed to enable
scalable, flexible and intelligent applications, running on
next-generation cloud architectures. Queries and joins are experessed
using the logical query language Datalog.

In this hands-on session, Ragnar Dahlén will give a brief introduction
to the technology then lead us through some interactive exercises.

You're welcome to come along just for the talk, but for even more fun
please bring along your laptop to join in the interactive session.

Beginners welcome, there will be help on hand if you're new to

On the day, you'll find us in the upstairs room at the Fountain. Note
that they no longer serve food in the evening.

    No worries Ray. It was a pleasure to meet you all, and hopefully some of what I showed was interesting. The conversations around the subject were very interesting for me. Thanks, Andrew

    Thank you, Andrew, for stepping in to show us some Datomic examples. It was really useful to hear some real-world experiences after al the tutorials and documentation I've been reading. Speaking of tutorials, for anyone wanting to work through some examples on their own, I found the tutorial on the Datomic web site very useful, and Day of Datomic looks interesting.

    Hello people,
    Unfortunately I have become urgently sick (possibly food poisoning) so I cannot attend tonight. I'm really sorry for this, I was really looking forward to playing around with clojure in the group.
    I hope you can still give datomic a go, maybe follow the one of the online tutorials.

    One useful thing could be to try the examples at

    which is a great introduction to the query language used by clojure.

    Again, apologise for this late cancellation from my side.

    I hope you have a fun evening anyway.

    Unfortunately Ragnar has been taken ill and won't be able to give his talk tonight. We'll still go ahead with the meetup, but I'm afraid we'll have to muddle through without his expertise on hand.

    Another commitment has come up so unfortunately won't be able to make it this evening. Hope you enjoy the evening.

    Ray was quicker than me, but just to clarify:

    My intention is to give a short introduction to datomic, focusing on the how, rather than the why. I'll try to provide some example stuff to play around with after the introduction, so make sure you have (at least) downloaded datomic beforehand if you want to follow along. I would also recommend that people download datomic console (a graphical interface to parts of datomic) which is available from:

    (requires an account)

    If you need help with installing or setting up datomic (or clojure), we'll be happy to help.

    It would be great not to stress the fountains wifi too much, so please download datomic beforehand if you can.

    As tomorrow's talk will include some practical exercises, it might be an idea to download Datomic before the meetup. You can get the free edition here:
