What is the best way to organize a MongoDB database (using Mongoose)?

Question

MongoDB

Hello! I have this question: how best to organize a database on MongoDB (Mongoose):
Let's say we have two entities: User (user) and UserProfile (user profile).
How best:
1. Divide User and UserProfile into two models
2. Do everything in one model, make something like this scheme:

{
username: {},
profile: {
   firstName: {},
   lastName: {}
}
}

Maybe this is not the best example, but still, could you tell me which approach is better? I assume 2, but not in all cases.

Answer 1

And why an extra level of nesting, what is the point of storing them separately.
In my life I came across both cases in both cases I wanted to shove rebar in the ass to programmers like you.
Make just one table with three fields without any idiotic nesting and different entities.
