SAP has taken on the challenge of mastering the tremendous growth in data volume of the past few years by developing the In-Memory technology for the analysis of large data volumes and the simultaneous reduction of IT costs.A

As a further development of the In-Memory technology, SAP has now introduced the SAP In-Memory appliance (SAP HANA).

Thanks to SAP HANA, large corporations can process large volumes of detailed data in order to analyze the course of business immediately after data generation.

The technologies applied to this effect  (SAP NetWeaver Search and Classification (TREX)) are able to search for information in unstructured as well as structured data.)

Given the many successful installations, this application was then developed further into the BWA (Business Warehouse Accelerator). Thus, new application scenarios can now be illustrated with this technology. Approx. 6% of all productive SAP BW systems already work with this technology today (state: 2011). We have received primarily positive feedback on this technology from our customers. Expectations towards performance and savings with regard to  data model maintenance have been met.

The core elements of this technology are:

  • Data is memorized completely in the main storage unit
  • Data is saved in logical data columns
  • Data maintenance and processing run parallel
  • Parallel operation is scalable
