What is SAP HANA?
SAP HANA is an innovative technology based on In-Memory Computing. In general terms, it involves transferring the management of huge data sets from the disk space into the operating memory.
The basic element of the SAP HANA platform is its unique SAP HANA In-Memory Database. The fundamental feature that distinguishes the SAP In-Memory Database from a classic relational database is that it resides entirely in RAM and uses the disk system for backup. This feature makes the speed of data operations a hundred times faster by eliminating disk input/output operations with database queries. In addition, SAP HANA includes computing accelerating elements that fully uses multi-core processor architecture, multithreading and rapid data access (SAP In-Memory Computing). The combination of the above technologies considerably accelerates access to data and provides results of complicated calculations in real time.
The development of the in-memory technology is enabled by the parallel development of the hardware layer. The SAP HANA platform requires dedicated and SAP certified servers – dubbed the ...
