In real-world applications, it often makes sense to show denormalized data, such as delimited lists, within the application's user interface.

Column Store Index, which improves performance of data warehouse queries several folds, was first introduced in SQL Server 2012. Unlike regular indexes or heaps, which store data in B-Tree structure (in row-wise fashion), the column store index stores data in columnar fashion and uses compression aggressively to reduce the disk I/O needed to serve the query request. In this article, Arshad Ali talks about the new enhanced columnstore index feature in SQL Server 2014.
