SAP Business Warehouse (abridge SAP BW) is SAP’s Enterprise Data Warehouse product. It can transform and consolidate business information from virtually any source system.[citation needed] It ran on industry standard RDBMS until version 7.3 at which point it began to transition onto SAP's HANA in-memory DBMS, particularly with the release of version 7.4.


In 1998 SAP released the first version SAP BW providing a model-driven approach to EDW which made data warehousing easier and more efficient, particularly for SAP R/3 data. Since then SAP BW has evolved to become a key component for thousands of companies. The following article provides the history of SAP BW from inception to the newer releases powered by SAP HANA.
