SAP HANA (high-performance analytic appliance) is an application that is designed process structured data from relational databases, both SAP and non-SAP, and applications and other systems rapidly. It has the ability 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. Due of this, data can be accessed quickly in real time by the applications that use HANA.
