BW on HANA Basics and Differences

206 Views

Hi All

I have a basic question regarding infocube structure before HANA and after HANA .

Befoe HANA The infocube strucutre is like the fact table is linked to SID tables via Dimension tables ,after HANA the infocube structure has changed and now the dimension tables has been removed and the fact tables are directly linked to SID tables .My doubts are as below

1.Why the Dimension tables are basically used in BW (is it only to reduce the data redundancy or any other reaosn )?.

2. Why Fact tables can't be linked to SID tables directly without Dimension tables in BW system without HANA.Why it is possible with HANA only.

Thanks
