Are there any good courses or literature on DWH, BI, OLAP?

Question

OLAP

Hello.
I work as a developer analyst. Recently, there was a need to use OLAP technology (there is a lot of data, queries do not work as fast as the user wants, for some time I used the result of the query as a connection and wrote data to the model, but the file naturally began to grow and this is also unacceptable). I did some digging in VS, created a cube, but I feel that not everything is going smoothly. Can you suggest any courses or literature to get ahead in this area fairly quickly?

Answer 1

Microsoft has a lot of material on OLAP SQL Server, this is their main feature, consider
Google and go
