SAP S4 HANA

SAP HANA (high-performance analytic appliance) is an application that uses in-memory database technology that allows the processing of massive amounts of real-time data in a short time. The in-memory computing engine allows HANA to process data stored in RAM as opposed to reading it from a disk.

SAP HANA is designed to process structured data from relational databases, both SAP and non-SAP, and applications and other systems rapidly. It is capable of using three styles of data replication depending on the source of the data – log-based, ETL-based, and trigger-based. The relocated structured data is stored directly in memory. Because of this, data can be accessed quickly in real-time by the applications that use HANA.
