Cognos is widely used by our Ellucian clients and is straightforward to integrate with the Data Cookbook. 

This established integration between Cognos Reports and the Data Cookbook enables your users to easily see documentation from the Cookbook without navigating away from the Cognos environment.  

Place a link on any Cognos Report that will show a summary of the Data Cookbook specification in a browser pop-up window.
Another level of integration is to embed that summary directly into the report.
