Thank you so much. I was struggling with learning reference approach but you made it completely clear to me.

Really excellent expatiation 👍

Awesome, thanks

[@groundtouche]

Quick question, why would I ever have Item referenced in sales with its price. The Item price would change eventually.. what do you suggest?

[@therodri595]

Excelent video , can you try to do more complex and advance agreggations ?

[@the_full_stack_junkie]

Will definitely look into this thanks for the comment!

[@jaggyjut]

wow a full crash course. Thanks. Could you create a tutorial on how to handle an update across two or more collections using a single query. For example if we have a users and posts collection and if we update the username in the users collections, the username in the posts collection should also get updated.

[@mohdhasib305]

hey i am stuck in same problem. did you resolve it?. If yes, please share link of the tutorial here.

[@ayeshazahid2421]

thank you so much for this video, I was looking for $loopups and how ref relation works and you solved my issue. but I have a question, can you suggest to me which approach I should need to use for a money wallet like every user have a wallet, so should I link users with the ref approach or embedded approach??

[@the_full_stack_junkie]

Hey man so basically this is whete mongodb shines there isnt really a right or wrong approach to your problem. But again i dont really know how the wallet works if it record only a balance then embedded should work fine. If you save transaction details then go for ref approach

@@the_full_stack_junkie thank you soo much , i didn't expect to get reply so fast

All good champ, I had little time on my hands💪🤓

[@ayeshazahid2421]

@@the_full_stack_junkie hello sir I have one more question, can you tell me what the difference between $lookup and .populate(). if we take your example then can we use .populate() too?? and which one best Thanks in advance

[@the_full_stack_junkie]

The $lookup is if you want to use the native mongodb driver aggregation api. And populate is a built in mongoose method that does the same but you are using mongoose implementation

[@kaybeek6417]

It's perfect!

[@AnkitBhardwajjgd]

thanks

[@frenchmike]

newbie question. I see organizations and projects in mongodb, then of course databases in projects etc. If I create a new web application for instance and I call it "workoutApp", do I create a new project named "workoutApp" and place all my db in my project or do I create and organization named 'workoutApp". in which case would I create a new organization ?? thanks

[@the_full_stack_junkie]

Hey man so this is personal preference. I would do it as creating a organization for production apps and one for development apps. This is just my way of organizing my mongo atlas instances.

[@emanuelmaricic9657]

Hello bro, how to create a user-users data relationship on MongoDB? In my example, I have users and articles. I want to be able to give every user permission to add article and list and update all his added articles. How do I connect those?

Are the same functionalities available in Mongoose?

[@the_full_stack_junkie]

Yes you can write vanilla Mongo Query Language in mongoose they do allow it yes.

What ever happened to 3NF?..

[@the_full_stack_junkie]

You can still normalize your data in the same way you would with SQL databases.
