SAP HANA (referred to as SAP High-Performance Analytic Appliance) is the new in-memory database (DB) platform from SAP. The SAP HANA platform allows companies to store and analyse large volumes of non-aggregated data in real-time with unprecedented performance. It is ideal for decision support & predictive analysis, this is proven by the fact that SAP’s datawarehouse solution, SAP NetWeaver BW 7.3 , was the first SAP application server component supported by the HANA platform.
A SAP HANA Appliance refers to HANA DB as delivered on partner certified hardware as an appliance.
SAP HANA DB incorporates a complete database management system (DBMS) that supports both columnar (ideal for OLAP) and row-based (for OLTP) data storage as its backbone and it supports business intelligence clients using multidimensional expressions (MDX) as well as business intelligence consumer services (BICS), the SAP interface for Business Objects solutions.
SAP HANA leverages recent hardware innovations such as multi-core CPUs which allow massive parallel processing and high capacity RAM, as well as new compression and parallel processing algorithms. The combination with column-based storage enables parallel execution using multiple processor cores, maximizing the use of computing resources available.
Important to mention is that HANA is a platform, including multiple analytical and application development services. The standard edition of the HANA platform already includes multiple analytical services like series data, operational process intelligence, data warehousing foundation, enterprise architecture designer and integration services.
The enterprise edition provides you with enterprise information management which includes known services like smart data integration (SDI) and smart data access (SDA). On top, you will have access to the full predictive library of HANA.
The HANA database services provides you with data modeling tools to build graphical views on top of your HANA tables or other views. These views can be modelled in such way to integrate any business logic.
