Transcript
BI Accelarator (BIA) • Redundant data store of a BI InfoCube on the BI accelerator server. • To improve the performance of BI queries when data is read from an InfoCube • Data of a BI InfoCube is made available as a BI accelerator index in a compressed but not aggregated form. • Consists of several, possibly split indexes that correspond to the tables of the enhanced star schema and a “logical” index which, depending on the definition of the star schema, contains the metadata of the BI accelerator index. • Instead of large number of aggregates for one particular InfoCube, you can use the BI accelerator to avoid this high maintenance effort.
