Joins 13 Ways

published on 2023/07/04

Relational (inner) joins are really common in the world of databases, and one weird thing about them is that it seems like everyone has a different idea of what they are. In this post I’ve aggregated a bunch of different definitions, ways of thinking about them, and ways of implementing them that will hopefully be interesting. They’re not without redundancy, some of them are arguably the same, but I think they’re all interesting perspectives nonetheless.
