Thorsten Lüdtke is an independent SAP BI architect and founder of BIPortal GmbH (https://bi-portal.com). He specializes in data warehouse architectures based on SAP BW/4HANA, SAP HANA, and SAP Data Intelligence. Thorsten entered the analytics field in 1997 as a MicroStrategy employee, developing applications for business intelligence. In 1999, he developed the first SAP RapidMarts solution (acquired by SAP BusinessObjects) based on SAP Business Information Warehouse 1.2B at Acta Technology in Silicon Valley. From 2002 to 2005, Thorsten worked as an SAP BI consultant and SAP BW trainer for SAP in numerous projects in Germany and the UK. In 2006 he started a joint venture with Bill Inmon as a member of the advisory board and presented the product (BI Master Data Management) at SAPPHIRE 2007 in Vienna. This event marks the beginning of his company, BIPortal GmbH.
After office hours, he enjoys classic AI books from the 70s and 80s, as he believes that those early concepts of symbolic computation can augment recent advantages in machine learning. Thorsten studied computer science at the State University of New York at Albany (SUNYA) and information systems at the Technical University of Braunschweig (TUBS) in Germany. Since then, he’s been looking for ways to use machine learning in business analytics, as it is now easy to do with SAP BW/4HANA.
