The connection between ECS and DBs wasn't lost on developers in the early days of ECS. I'm reminded of Scott Bilias's 2002 ECS presentation: A Data-Driven Game Object System[1] which clearly says, "This is a database." In my mind, there's a pedagogical gap in OOP where ontologies are formed using classes and this almost never works in real life applications (no in real life for that matter). We almost always construct ontological relations using predicates not rigid hierarchies. For this, ECS tends to be flexible, and expressive enough to be a pragmatic choice. 1. https://www.gamedevs.org/uploads/data-driven-game-object-system.pdf https://www.gamedevs.org/uploads/data-driven-game-object-sys...
