Hello Sergio,

You are right, the primary key is an artifical (surrogate) primary key.

To be honest, I don't know the reason. 

The best way to get the answer is to ask directly in the article: https://www.vertabelo.com/blog/a-dating-app-data-model/

Hope this helps,

Adam

Hello Scott,

I have tried to reproduce the error, without success.

What browser and OS are you using?

Hello,

It should be possible.
1. Please open the model.

3. Select database.

4. Save changes.

Hope this helps,

Adam
