SAP BI Accelerator


In computing, the SAP BW Accelerator is a computer appliance - preinstalled software on predefined hardware - which is used to speed up OLAP queries. The software was initially known as the BI Accelerater.
SAP BW Accelerator includes indexes that are vertically inverted reproductions of all
the data included in InfoCubes. Note that there is no relational or other database management systems in BW
Accelerator. There is only a file system, and indexes are essentially held as flat files.
The second primary component of SAP BW Accelerator is the engine that processes
the queries in memory - it uses the SAP TREX search engine. The software is running on an expandable rack of blade
servers. The operating system used for BW Accelerator is 64-bit SUSE Linux Enterprise Server.
