Best-practice modeling

[Anonymous]

Hi,

I have a question with regard to best-practice modeling in PowerBI.
These are the best-practices I’m using;

1 Convert relational models to star model.
2 Convert snowflake models to star model.
3 Transfer facts from dimension tables to the fact table.
4 Use bi-directional relations instead of flattening tables.
5 Flatten tables if the model is too complex(Too many dimensions/facts and relations). Make joins to reduce the number of dimensions, facts and relations.
6 Set the right data types.
7 Data cleansing. 

Is the list correct? Am I missing any?

They're all valid points, except for number 4.

I would discourage the use of bi-directional filters unless you've a very solid understanding of DAX

Hi LivioLanzo,

Thanks for the reply. Right now, I'm testing bi-directional filters in different situations.
To increase my understandig of how exactly it works.

Thanks again.
