Ever since BW on HANA had been introduced, I read many articles discussing the improvement that it can deliver. These articles provided these conceptual experiences that resulted in specific benefits, features and overall improvements. I recently had the experience to execute a true POC that compared a BW on Oracle system with a BW on HANA environment. This was the first time I was able to turn the conceptual into practical and I wanted to share these results with you. Though the system that I was working with was not terabytes, I think I was able to clearly quantify the HANA benefit. Let me know what you think and I hope that you enjoy.
