IBM Cognos Express Xcelerator

IBM Cognos Express Xcelerator extends and transforms the Microsoft Excel front-end with a powerful in-memory analytics engine.

It's perfectly suited for multidimensional business analysis and "what-if" scenario modeling, enabling a new level of insight and action for better business outcomes.
Users can work within an Excel environment to create custom analysis and build their own “what-if” business scenarios. This approach allows business users to use existing Excel skills and investments while overcoming the risks and limitations of spreadsheet-only processes.
