Clojure NYC had another great talk last night with Michael Gaare of Ladders introducing his library sqlium. Michael has taken his experience with Datomic and has created a DSL for querying SQL databases with a Dataomic-like flavor.
The source for the library was just put up on GitHub last night at https://github.com/TheLadders/sqlium. It will be interesting to see how the library does as others start using it.
As a next step, it would be good if the source Michael demonstrated last night which used the MusicBrainz data set was published somewhere for review as well.
