Projet about ER model into STAR model

[siem]

Hello, I got on qliksense 5 tables  but it's a ER model.

And I have to transform this ER model into star model.

It's first time, I just discover today what is a star model.

I would like to know if you have some project to link me on youtube or tuto about how transform on qliksense a ER database into a STAR database.

Thanks in advance
