Microsoft Dynamics GP with SQL Server 2012 and the Columnstore Index
...
The release of Microsoft Dynamics GP 2013 has introduced many new improvements. There are also some robust improvements for SQL 2012, which help support Microsoft Dynamics GP in the data warehouse.

New with SQL 2012, the xVelocity columnstore index does exactly as the name implies – stores data by columns instead traditional rows. How does this help you with the Microsoft Dynamics GP data warehouse? Columnstore indexes typically span all columns of a table, they do not require a primary key, and the column order has no effect on the index performance because SQL Server 2012’s black box processing automatically organizes and compresses the data in an extremely efficient manner.

How efficient is it? A columnstore index on a large table can increase the performance of OLTP transactions by as much as 100 times, and can span as many as 1024 columns.

"can increase the performance of OLTP transactions by as much as 100 times" - похоже через чур оптимистично.

Columnstore indexes can transform the data warehousing experience for users by enabling faster performance for common data warehousing queries such as filtering, aggregating, grouping, and star-join queries.

Topic Status: Some information in this topic is pre-release and subject to change in future releases. Pre-release information describes new features or changes to existing features in Microsoft SQL Server 2014.

The xVelocity memory optimized columnstore index stores and manages data by using column-based data storage and column-based query processing in SQL Server. Use the columnstore index to achieve up to 10x query performance gains over traditional row-oriented storage, and up to 7x data compression over the uncompressed data size.
...
We view the clustered columnstore index as the standard for storing large data warehousing fact tables, and expect it will be used in most data warehousing scenarios.
