Firebase for nested data storage?

Discuss
#1

Ok, I don’t know if ‘branched/tree’ data storage makes any sense, coz I made it up now. I worked with firebase a looong time ago. But now when I opened it, many new things have been added. (Something like collections, documents, fields, etc etc ie cloud firestore)
I know how to simply store and get values like this:

UserID=password
Userid2=password2
Userid3=password3
Etc etc.

But I need to know if I can do this:
UserID{
Name=bfc
Password=passwordexample
Contactno=12638392028
Marks:{
Test1=23
Test2 =55
}
}

I hope you are getting the idea. I want multiple variables to be linked with a unique ID, and through that, I should be able to get data from all those variable.

It’s easy to do this in Airtable, but since only 5 requests can be made/sec, I don’t want to take that risk.

Can anyone help me with this nested/branched (idk) data storage problem?

This guide might help you

There’s some stuff about creating groups of data which might address your issue.

Thank you so much! Does this mean that if I store a value with tag ‘marks/exam1’ , ‘exam1’ will be created as a child of ‘marks’?

Yes.
You can separate child tags with “/”

I got one more doubt. How many nested child tags can you make? I mean can you do this:
Parent{
Child{
Grandchild=happy
}
}

You can make an infinite number of child tags. But it is generally advised to keep the nesting to a max of 3 levels. Due to the way Firebase works, fetching a tag first fetches all its parents. So multiple nested layers can slow down your app significantly.
