The honest decision framework, not another flame war.
The SQL vs NoSQL debate has been running for 15 years and it still generates more heat than light. Here's the framework that actually helps you decide.
The Real Question
It's not "SQL or NoSQL." It's: what does your access pattern look like?
If your application is mostly reading and writing related data through well-defined queries — orders with line items, users with addresses, products with categories — relational databases are purpose-built for this. JOINs are not expensive when they're indexed. Transactions are not slow when they're scoped correctly. PostgreSQL handles 50 million rows comfortably on a single node.
