I’ve been reading through the SQL and NoSQL parts, and I really enjoyed them. Personally, I would have loved to see more detailed examples or code snippets to make the concepts even clearer.
From my own experience, NoSQL has worked well for blog-style sites where flexibility matters, while SQL tends to be a better fit for payments or larger, more structured systems. So it was interesting to see how you approached that distinction.
Thanks for putting this together — it’s a great resource.
