Comparison Between BW and Datasphere

[#1]

Hello,

I am currently working on a project based on SAP Datasphere.
Datasphere is one of SAP’s data solutions and is often compared to SAP BW (Business Warehouse).
Since I have only worked with Datasphere, I am not very familiar with BW.

Therefore, I would like to understand the differences in roles and functionalities between BW and Datasphere.
Does BW have limitations or difficulties in connecting to external (non-SAP) systems?
What are the key reasons why customers choose BW versus Datasphere?
