BIW was a data warehousing and business intelligence concept and solution introduced by SAP before it evolved into more advanced and integrated offerings. It aimed to provide organizations with a centralized repository for collecting, storing, and analyzing business data from various sources. It’s important to note that the term BIW is now largely obsolete, as SAP has moved forward with more advanced and integrated solutions for data warehousing (SAP BW) and business intelligence (SAP BusinessObjects, SAP Analytics Cloud, etc.).
