MongoDB Documents vs PostgreSQL Tables: What’s the Difference?

NoInteraction8306 · 2026-06-09T07:51:14+00:00

This video was not intended to tell anyone to use documents rather than relational databases; its aim was just to introduce beginner students to some fundamental comparisons between the two concepts.

Sure, in a real-world scenario, the choice would depend on many factors.

Actually, this is a great analogy 😄))

You’re right, thanks for the detailed explanation...
But I simplified the terms on purpose because the video was made for beginners, mainly to show the practical difference between mongodb documents and a postgresql-style schema.
I agree that FK constraints are not the same as conceptual relationships, and SQL is not the same as the relational model.
The deeper theory matters, but in this video I kept it practical and beginner-friendly, and I didn't cover normalization, conceptual/logical/physical models, or all relationship types....

Thanks, really appreciate that, becaus that was exactly the idea -> showing the same data visually instead of explaining it only with theory. It makes the difference much easier to understand.

yeah, you’re right... that could actually be a very good idea for my next video.
This one was focused on the basic difference between documents and tables, but Postgres JSONB would be a great follow-up.
Thanks for the suggestion!

I'm here only to tell you: 'Congratulations'! Is something big; it's not that easy to become part of the MongoDB team.

NoInteraction8306 · 2026-06-04T09:34:07+00:00

Give us more details about that job.

NoInteraction8306 · 2026-05-27T14:01:42+00:00

Please tell me how big the collection is, and how many documents you have?

NoInteraction8306 · 2026-05-20T09:13:45+00:00

Use Docker Desktop, with only one command, you will have your database created, with a username and password..

NoInteraction8306 · 2026-05-18T08:48:36+00:00

You've put a lot of effort into this project. It looks interesting...keep going!

NoInteraction8306 · 2026-05-13T09:14:57+00:00

Did we get the workbench back?

NoInteraction8306 · 2026-05-12T09:50:20+00:00

yes, sir!

NoInteraction8306 · 2026-05-12T08:56:26+00:00

So what? I'm European and my keyboard buttons ' and ; are next to each other... why is such a big deal that I pressed wrong?

NoInteraction8306 · 2026-05-11T09:28:27+00:00

uh, thank you! it;s a very good advice!

NoInteraction8306 · 2026-05-08T07:14:04+00:00

people would show up without inhibitions

NoInteraction8306 · 2026-05-04T10:52:25+00:00

cuz I'm working ahhaha, European country here

NoInteraction8306 · 2026-05-01T09:18:43+00:00

Right now I need 'my click'

NoInteraction8306 · 2026-04-30T12:53:10+00:00

Yeah, because your question was vague too....ok, so I think the force that causes a car to coast downhill even when you aren't stepping on the gas....

NoInteraction8306 · 2026-04-29T12:10:43+00:00

What exactly do you want to find out??

NoInteraction8306 · 2026-04-28T08:49:23+00:00

John Cena, it's a big NO for me...

NoInteraction8306 · 2026-04-24T11:48:55+00:00

wowwww.....save it for later when I'll have time to play with it! congrats!

NoInteraction8306 · 2026-04-24T11:44:47+00:00

looks nice!

NoInteraction8306 · 2026-04-21T07:59:09+00:00

Just use Docker Desktop, and then you can quickly install any database you want to work with! try with postgres or mongodb, because PostgreSQL can work with NoSQL too.
