This is exactly my impression after taking a quick glance through these articles as well. If anyone is curious and would like to see a practical demonstration of this data-oriented approach of modelling problems, I highly recommend this talk from Mark Bastian in Clojure/conj 2015: https://www.youtube.com/watch?v=Tb823aqgX_0 https://www.youtube.com/watch?v=Tb823aqgX_0 In it, he contrasts the data-oriented modelling approach with a traditional OOP approach for implementing a board game, and was able to come up with a complete implementation of the game with the former approach that was shorter than even the structural boilerplate for the OOP version. Another related talk that I loved was Chris Granger's 2013 talk on Light Table: https://www.youtube.com/watch?v=V1Eu9vZaDYw https://www.youtube.com/watch?v=V1Eu9vZaDYw Where he walks through his process of building a game in ClojureScript using an Entity-Component-System architecture, which is very well suited to this data oriented modeling approach.
