SAP HANA, short for ‘High Performance Analytic Appliance’ is an in-memory, column- oriented, relational database management system . SAP HANA originates from developed or acquired technologies, including TREX search engine, an in-memory column-oriented search engine, P*TIME, an in-memory OLTP database acquired by SAP in 2005, and MaxDB with its in-memory liveCache engine. In May 2013, a software as a service offering called the HANA Enterprise Cloud service was announced. Rather than versioning, the software utilizes service packs.
SAP HANA not only combines database, data processing, and application platform capabilities but provides an excellent platform for predictive, text processing, planning, spatial, and business analytics.
