SQL vs NoSQL

Avoid This Debate Right Away

When it's time to choose a database in the middle of your design, don't start digging into the exact type of database you need. That's a show-off topic you can come back to later if there's time.

While you're still sketching the system, leave the database as a placeholder. Say: "I'll use a relational database here — let's say PostgreSQL — and we can revisit the choice once we see the full picture." This shows you're aware that different options exist, but you're not going to burn 5 minutes on a SQL vs NoSQL debate before the system is even drawn.
