This post is not addressing the right question. Think of databases as storage space, like wardrobes. The sql database will allow to store your clothes in spare parts each with its own dedicated space, allowing you to quickly calculate the sum of all stripes on all your socks. That's great but on the other hand, if you want an outfit you have to put it together, starting by sewing the sleeves on the shirt. On the other the NoSQL wardrobe will have various boxes where you can put any cloth you want. Now it's up to you to tidy the whole thing. If you want you can put full outfits in the box so that you don't have to think much about what to wear. However to count the number of stripes on your socks, you'll have to go through the whole wardrobe. The point is: It's not the fault of the wardrobe if your room is a mess
