Read the HarperDB teams’ thoughts on database technology topics such as SQL, NOSQL, Edge Computing, IoT, Industry 4.0, and more
After coming up with the worst pun ever made in the database community, this title, to talk about one of if not the most powerful features in relational databases: the SQL join. I believe that the joins are a big reason the relational databases have stayed so relevant in a world where everyone seems to be talking Big Data. NoSQL databases cannot perform join operations. Sure there are a ton of articles out there describing work arounds, but at the end of the day they all come to the same conclusion and that is if you need to join, you need a relational database.
