Dear Experts,
I am new to IDT. I have started getting the concepts.
My doubt is, OLAP Business layer will created without using Data foundation.
In this case, don't we need schema for the relevant tables huh? . How the normalization of tables and joins will be handled? .
can anyone please explain me ?..
Thanks in Advance!

Hi
while creating universe you have two options to select the connections
As per your requirement you have chosen OLAP Connection i think.
So OLAP connections to connect to an SAP NetWeaver BW data source based on a BW server, a cube, and a BEx query.
If your backed as BW ...then No business layer or universe is required to access BEx queries. We can directly select the BEx query as a data source.
You can do all the calculations & data restriction (CKF, RKF, Filters and Variables) and use Bex Q as direct source.
Please find the below link. To know the difference b/w OLAP and Relational connections and what are the advantages using the OLAP connection.
SAP BW is an OLAP vs. Relation connection

For OLAP Business layer, we use OLAP connection to info providers in SAP BW. Hence the structure is directly referenced from the structure of providers in SAP BW.
