BI accelerator solutions like the SAP NetWeaver database engine TREX achieve high performance when processing complex analytic queries in large data warehouses. They do so with a combination of column-oriented data organization, memory-based processing, and a scalable multiserver architecture. The use of data compression techniques further reduces both memory consumption and processing time. In this paper we study query operators like scan and aggregation on compressed data structures implemented in TREX.
