Datomic https://www.datomic.com/ a not-sql cloud database with a robust and principled information model competitive in use case with rdbms. In agreement with your parent, Datomic is very different and most commonly used from the Clojure programming language which rejects similarly much mainstream thought/practices. https://clojure.org/ https://clojure.org/about/state The talk Database as a Value https://www.infoq.com/presentations/Datomic-Database-Value/ is a good starting point to understand the flaws in relational model implementations (it has been argued on r/clojure that Datomic more faithfully implements relational algebra than RDBMS does – https://www.reddit.com/r/Clojure/comments/99f4ln/datomic_is_...)

Counter-intuitively Datomic is in violent agreement with /u/rqmedes where he said "A better alternative is having the data, data model and business logic tightly bound in one place. Not separated in multiple "tiers"" – Datomic inverts/unbundles the standard database architecture such that the cached database index values are distributed out and co-located with your application code such that database queries are amortized to local cost. Immutability in the database is how this is possible without sacrificing strong consistency, basically if git were a database you end up at Datomic.
