In this episode, we are pleased to speak with Andreas Kremer, Co-Founder of ITTM Solutions, Luxembourg, and Mark Rogers, ETL Product Manager, Imosphere, UK, representing two of our small-to-medium-sized-enterprises (SMEs), who are part of the expanding network of EHDEN-certified SMEs in Europe. They both share the impetus for joining this EHDEN programme, and discuss the experience and learning from working with Data Partners on mapping their source data to the OMOP common data model. Importantly, there are many levels of engagement, support and development beyond the focus on an ETL. Lastly, we speak about the future role of SMEs in European research more widely, and their integral role in enabling programmes, projects and initiatives utilising real world data.
