I completely, fully get what you're saying and I've done this trade off between various data structures for a very long time, but my question wasn't about that, but the difference between data structures and data models. Put simply, it was a question of terminology used rather than technique applied.

I guess in the way I use it, choosing a data structure is about the complexity/performance of operations you're going to do with a collection of objects, and choosing a data model is more about the meaning of fields, and what entities and relations between them you have in the first place, sort of like `CREATE INDEX` vs `CREATE TABLE`
