SAP HANA is an in-memory database and application platform, which is for many operations 10-1000x faster than a regular database like Oracle on the same hardware. This allows simplification of design and operations, as well as real-time business applications. Customers can finally begin to reduce IT complexity by removing the need for separate and multiple Application Servers, Operational Data Stores, Datamarts and complex BI Tool implementations.
SAP HANA is a “reinvention” of the database, based on 30 years of technology improvements, research and development. It allows the build of applications that are not possible on traditional RDBMS, and the renewal of existing applications like the SAP Business Suite.
Why did SAP build a database?
SAP co-founder and Chairman Hasso Plattner believed that if a database could be built with a zero response time, that business applications would be written fundamentally differently – and IT landscapes could be simplified. The research institution at the Hasso Plattner Institution in Potsdam theorized that with modern computers and software design, this would be very nearly possible.
SAP makes business applications and since it was clear that none of the incumbent software vendors like Oracle would write such a database and application platform, they needed to build their own. In addition, this would be the springboard for a complete renewal and simplifying of SAP’s applications to take them through the next 20 years.
Is SAP HANA just a database?
No. When SAP went to build HANA, they realized that the next generation of business applications would require a much more integrated approach than in the past.
SAP HANA contains – out of the box – the building blocks for entire enterprise applications. HANA can take care of the requirements that would be served by many layers in other application platforms, including transactional databases, reporting databases, integration layers, search, predictive and web. All of this is served up working out the box, with a single installation.
