SAP HANA was previously called SAP High-Performance Analytic Appliance
SAP HANA is an in-memory platform for processing high volumes of data in real-time. HANA allows data analysts to query large volumes of data in real-time. HANA's in-memory database infrastructure frees analysts from having to load or write-back data. HANA's columnar-based data store is ACID compliant and supports industry standards such as structured query language (SQL) and multi-dimensional expressions (MDX).
HANA also includes a programming component that allows a company's IT department to create and run customized application programs on top of HANA, as well as a suite of predictive, spatial and text analytics libraries across multiple data sources. Because HANA can run in parallel to a source SAPERP application, analysts can access real-time operational and transactional data and not have to wait for a daily or weekly report to run.
SAP HANA can be deployed on-site as an appliance or purchased as a managed cloud or hybrid- cloud service.
SAP HANA has completely transformed the database industry by combining database, data processing, and application platform capabilities in a single in-memory platform. The platform also provides libraries for predictive, planning, text processing, spatial, and business analytics -- all on the same architecture.
This makes it possible for applications and analytics to be rethought without information processing latency, and sense-and-response solutions can work on massive quantities of real-time data for immediate answers without building pre-aggregates. Simply put -- this makes SAP HANA the platform for building and deploying next-generation, real-time applications and analytics.
