Hello everyone,


I'm starting BI with Power BI.

Now, i'm learning about concepts of Datawarehouse, Datamart and cube. I could understand that these 3 notions can be built with the OLAP modeling model, I am wrong ??


For my case, I have a SQL Server database,, which contains my Datawarehouse. In Power BI Desktop, I connect a new repport with my SQL Server Database in DirectQuery , i select the dimensions tables and my fact table with which i want to work. Next, these tables appear in the model section and it's at this moment that's i start to create a dataset whith relation (star model) , measures and calculated columns.


I want to know if this dataset is the same as a OLAP cube ?

If i am wrong, i want to know if is it possible to create a OLAP cube in power BI ?


thank you for your answers

For smaller dataset, it's perfectly fine to load data into powerbi and create a model. But if data is huge you can create an SSAS tabular model connect to PowerBI.


Appreciate a Kudos! 🙂
If this helps and resolves the issue, please mark it as a Solution! 🙂

Thank you for this answer, but that does not answer my questions which are :


I want to know if the dataset taht we build in Power BI Desktop  is the same as a OLAP cube built in SSAS ?

If it's not the same, i want to know if is it possible to create a OLAP cube in power BI ?
