SAP HANA, short for "High-Performance Analytic Appliance" is an in-memory, column-oriented, relational database management system developed and marketed by SAP SE.[1][2] It is massively parallel, thus exploiting the maximum out of multicore processors and subsequently enabling very fast query execution.
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.[3][4] In 2008, teams from SAP SE working with Hasso Plattner Institute and Stanford University demonstrated an application architecture for real-time analytics and aggregation, mentioned as "Hasso's New Architecture" in SAP executive Vishal Sikka's blog. Before the name HANA settled in, people referred to this product as New Database.[5]
The product was officially announced in May 2010. In November 2010, SAP SE announced the release of SAP HANA 1.0, an in-memory appliance for business applications and business Intelligenceallowing real-time response.[6] The first product shipped in late November 2010.[4][7] By mid-2011, the technology had attracted interest but the conservative business customers still considered it "in early days".[8] HANA support for SAP NetWeaver Business Warehouse was announced in September 2011 for availability by November.[9]
In 2012, SAP promoted aspects of cloud computing.[10] In October 2012, SAP announced a variant called HANA One that used a smaller amount of memory on Amazon Web Services for an hourly fee.[11]
In January 2013, SAP enterprise resource planning software from its Business Suite was announced for HANA, and became available by May.[12][13] In May 2013, a software as a service offering called the HANA Enterprise Cloud service was announced.[14]
