SAP HANA Overview
HANA is a brand new product residing on “off the shelf” IBM and HP hardware
In the current version - Data can be fed into HANA by:• replicating the Database Logs from the OLTP via Sybase Replication Server
(currently only DB2)• ETL (i.e. from a SAP BW source)
HANA end game is to replace the R3 Database and BW solution and provide a R3 HANA with views
Although HANA is a SAP product, it inherits no content and utilises no proprietary SAP BW concepts or ABAP
HANA does not create data it only reads data via SQL views HANA is built on column store in-memory technology
