SAP HANA is SAP's in-memory, column-oriented database and application platform. By keeping data in RAM and processing it in columns, it runs analytics and transactions on the same data in real time. It is the mandatory database underneath SAP S/4HANA and BW/4HANA.
SAP HANA (High-performance ANalytic Appliance) is an in-memory database. Traditional databases store data on disk and load rows into memory as needed; SAP HANA keeps the working data set in RAM and stores it by column rather than by row. That combination lets it aggregate huge tables and serve both transactional (OLTP) and analytical (OLAP) workloads on a single copy of the data, without the overhead of moving data into a separate analytics store.
SAP HANA is not just a database — it is also an application platform with built-in engines for advanced analytics, spatial data, graph, text search, and predictive functions. Business logic can run inside the database ("code pushdown"), which is a core idea behind S/4HANA's simplified data model.
Crucially, SAP HANA is the only database supported by SAP S/4HANA and SAP BW/4HANA. An organization moving off SAP ECC to S/4HANA is therefore also adopting SAP HANA, which changes how the system is sized, tuned, backed up, and operated day to day — the Basis and infrastructure disciplines this site focuses on.
