This isn't a helpful abstraction. Electricity is just electrons after all, why think about how you're going to wire your house when it's all just atoms? Read a bunch of books on quantum physics, then become an electrician /s

Isn't that the entire reason for articles like this? eg: If you have data with large amounts of relations a no-sql database probably isn't the right approach.

Absolutely, if just for knowledge's sake, but these are largely not needed if you understand the high level use cases for any given DB. It's cool if you understand B-Trees but not strictly needed to use sql. In fact, many would this this not helpful.
