IBM Cognos Business Intelligence components communicate with each other (and with any additional applications integrated with IBM Cognos BI) using the BI Bus. The BI Bus is not a software component in the traditional sense; rather, it is a set of protocols that govern communications among IBM Cognos services.
Esri Maps for IBM Cognos leverages the capabilities of the BI Bus in order to augment IBM Cognos reports with maps and data.
