Hello guys, Sap Business Suite 4 SAP HANA is the acronym for SAP Business Suite 4 SAP HANA. Similar to the shift from SAP R/2 to SAP R/3, it ushers in the next significant wave of innovation for SAP clients. SAP HANA (High-performance Analytic Appliance) is a multi-model database that keeps data in memory rather than on disc. This allows for far quicker data processing than traditional disk-based data systems, allowing for sophisticated, real-time analytics. SAP ECC, often known as SAP ERP, is SAP Business Suite's fundamental ERP software. SAP ECC can operate on Oracle, however S/4HANA can only run on HANA. As a result, some businesses will most likely have to change their business practices.
