SAP Business Intelligence / BusinessObjects (SAP BI/BO) is an enterprise-grade suite of front-end reporting and analytics tools built on SAP's data infrastructure, connecting to multiple data sources and turning raw data into structured reports and actionable insight.
The reference separates the two halves of the name: SAP BI, the server-side platform that manages security, scheduling, and content, and SAP BusinessObjects, the client-facing tools acquired with Business Objects S.A. in 2008 that end users and developers work with directly.
It then outlines the key tools: Web Intelligence for browser-based ad-hoc reporting on Universes, Crystal Reports for pixel-perfect formatted reports, SAP Lumira for visualization and data blending, Analysis for Office for OLAP analysis on SAP BW and HANA inside Excel and PowerPoint, and the Central Management Console for administration, scheduling, and auditing.
The full reference is available above as a PDF. See also "SAP Real-Time Analytics Tools and Reporting: SAC, Datasphere, HANA Cloud, and BusinessObjects" in the Resource Library.
