@thom.code: SQL vs NoSQL: Why Relational Databases Aren't Always Enough In this video, I break down non-relational databases and when to use them over traditional SQL. We start by comparing relational and non-relational approaches, then look at the limitations that push us beyond relational models. From there, I walk through each type of non-relational database, object storage, document stores, key-value stores, and wide-column stores, covering how each one works, their tradeoffs, and the use cases where they excel. By the end, you'll know exactly which database type to reach for in any system design scenario.
