Which option has more performance: 2 tables with relationship or 1 table with columns from 2 tables?

All the options works for my case, but I wanna know which option is more performatic?

Case 1: 2 tables with a relationship

Case 2: Just 1 table with values from 2 tables

@gluizqueiroz as a  best practice you want to keep your dimension and fact seperate so first design is better. Think if you have another data table which has customer with it and you need to compare sales vs. <new data>, in that case it will be easy if you customer in seperate table.

If my solution proved useful, I'd be delighted to receive Kudos. When you put effort into asking a question, it's equally thoughtful to acknowledge and give Kudos to the individual who helped you solve the problem. It's a small gesture that shows appreciation and encouragement! ❤
