Hello,
I would like to know if my data analysis method in Power BI is correct.
In the picture I presented my data model which I took from the database. This is a "clean" model without any conversion.
As you can see it is not a star model but everything in it works. Relationships work properly.
I have a question about data borrow / processing. A better solution would be to use go-between model in data acquisition?
I mean taking data from a database and aggregate it with some process between production database and power bi in which they will calculate the values and will not have to calculate them already in the power bi.
Currently in my model there are many measures and computational columns that cause the dashboard to slow action.
