SAP HANA is an in-memory, column-oriented relational database management system from SAP. Data is held in main memory, which enables fast access and querying. Besides storage and SQL, HANA offers predictive, spatial, text, streaming and graph analytics, ETL and an application server. It is used for real-time analytics and transaction processing and underpins SAP applications. HANA can run on-premises, as a certified hardware appliance or on existing hardware, or in the cloud with providers including AWS, Microsoft Azure and Google Cloud.
SAP SE is headquartered in Walldorf, Germany, and is a European company (SE). HANA is proprietary commercial software, licensed as Runtime or Full Use; an Express Edition is free for productive use up to 32 GB of RAM. Because SAP itself is based in the EU, it is subject to European law. If you consume HANA through a US hyperscaler, however, that adds a further party with its own jurisdiction to the chain, whereas on-premises use keeps the data entirely under your own control.
