Using SQL Server 2012 Column-Store with SAP BW
SQL Server 2012 introduced a new storage format for data. Besides the traditional row-oriented store, there is now also a column-oriented store available. The column-oriented store is optimized for aggregating mass data, while the row-oriented store can be optimally used when accessing just a single row. SQL Server 2012 column-store support has been integrated into all major SAP BW releases. You can now benefit from increased query performance and reduced disk space requirements.
