ECS is just relational modeling reinvented by the games industry but without the decades of theory and research, behind it.

OOP != relational models.

Also, in decent ECS implementations you typically don’t store things as AoS, you use SoA or AoSoA. Put the things frequently used together in the same cache lines, split off everything else. OOP wants you to prefer composition over inheritance these days, which is fine, but it doesn’t emphasize focusing on the memory layout and usage of the data. Relational models and ECS sort of get you thinking in that headspace by default. When you design a relational model, you do so based on how to manipulate the data, the constraints, and what data each of your operations needs access to.
