A Business Information Warehouse is a central system that collects, transforms, and stores business data from multiple sources for reporting, analytics, and strategic decision-making.
It enables organisations to analyse accurate, historical, and real-time data without impacting operational systems.

This guide explains what a Business Information Warehouse is, how SAP Business Warehouse (SAP BW) works, its benefits, evolution, and how UK businesses use it today.

A Business Information Warehouse (BIW) is an enterprise-level data warehousing solution designed to:
