What type of database is better to use?

Question

API

Hello, the essence of the question is this: there is data that comes from the VK Callback API. Some of them intersect (i.e. the same, for example, user id), and some are unique. All these data must be entered into the database (MySQL). I was advised to use a relational database type in order to avoid overflow, but I just can't figure out how to link the data that comes to me. I drew up a diagram, is it correct?

Actually more about the incoming data here .
Since I can’t normally compose a relational database, I would like to know what will be bad if I just enter incoming data into tables? Well, if everything goes very badly, I would like to get help in compiling a relational database. Thanks in advance!

1 Incorrect term "Database type", you can read more about the database here
2 MySQL is a database management system, and just relational.
3 The scheme in the photo does not carry any information. An example of a correct physical database model can be viewed here .
4 To imagine what threatens to simply enter data into tables, draw on paper a couple of tables that have links to each other with a couple of lines. Then add/remove a row in one table and check if the data is correct.
