OLAP for WPF and Silverlight is a suite of Silverlight controls that provide analytical processing features similar to those found in Microsoft Excel’s Pivot Tables and Pivot Charts. Asynchronous processing improves the performance of the controls as multiple processes can occur simultaneously on separate threads.  

For example: In case of synchronous processing, when you make any heavy update, the entire application stops responding to any action made by the user till the update is completed. In case of C1Olap, that supports asynchronous processing, when you make any heavy update (such as adding multiple fields to row or column box of a C1OlapPage), the application responds to all user actions even while the update is in progress.

OLAP for WPF and Silverlight takes raw data in any format and provides an easy-to-use interface so users can quickly and intuitively create summaries that display the data in different ways, uncovering trends and providing valuable insights interactively. As the user modifies the way in which he wants to see the data, OLAP for WPF and Silverlight instantly provides pivot grids and charts (and soon reporting) that can be saved, exported, or printed.
