I haven't used Datomic but I thought its entire premise is that the data is immutable and thus history/versioning was baked in. Am I missing something?

- ibdknox 11y agoThat is indeed the premise of Datomic, so I'm not sure how that would be a differentiator in this case. Beyond that, it's hard to make any statements on the difference between the query languages without more examples.
- david927 11y agoBaked-in as part of the language; the query language is where it stands out. I'll get you examples of that.
- ibdknox 11y agoFWIW, You can get transaction-time and the associated wall clock time in datomic's query language as well, though admittedly I can imagine cleaner ways of doing it :) http://stackoverflow.com/questions/11025434/in-datomic-how-do-i-get-a-timeline-view-of-the-changes-made-to-the-values-of-a http://stackoverflow.com/questions/11025434/in-datomic-how-d...
- david927 11y agoCool; I didn't know that. Thanks, Chris. I'm sorry we missed you at coffee on Saturday. The next one is in two months -- hope to see you then if you have time.
