The advent of hybrid transactional/analytical processing (HTAP) systems has reshaped enterprise data management, breaking the wall between transaction processing and analytics. This paper explores the co-innovation between enterprise applications and databases to advance HTAP architecture and drive its scalable adoption, as exemplified by SAP S/4HANA powered by SAP HANA. At the core of this innovation lies the Virtual Data Model (VDM), which simplifies the formulation of analytical queries directly over transactional data, making HTAP databases more accessible to application developers.
