Two-day German conference for data scientists, data engineers and data analytics teams at KOMED im MediaPark, Cologne, 7-8 October. 40+ speakers from Siemens, AUDI, E.ON and inovex covering agentic analytics, AI agents for data, data quality, data contracts and modern data stack architectures.
data2day is the joint annual conference organised by Rheinwerk Verlag GmbH and Heise Medien GmbH for German-speaking data science and data engineering professionals. The 2026 edition takes place 7-8 October at KOMED im MediaPark in Cologne, offering foundational content for practitioners entering data roles and advanced sessions for experienced data teams. The 2026 programme reflects a structural shift in the German data community toward agentic analytics, AI agent integration into data workflows and modern open data stack architectures.
Programme themes for 2026:
The conference targets data scientists and data engineers at all experience levels, with equal coverage of entry-level and advanced content. Analytics engineers, data team leads and data platform architects also attend. The Cologne location and DACH-region orientation means the audience is predominantly German-speaking, drawing from corporate data teams across manufacturing, retail, energy and technology sectors.
Both. The programme balances conceptual architecture content (semantic layers, data mesh, data contracts) with tool-specific sessions on popular frameworks. Enterprise case studies from Siemens, AUDI and E.ON ground the content in real deployment contexts.
The programme focuses on data engineering and analytics rather than model training and ML operations. ML engineers seeking MLOps or model deployment content will find limited overlap; those responsible for data pipelines that feed ML systems will find directly relevant content.
KOMED is a conference and event venue at Im Mediapark 7, 50670 Köln, in Cologne's MediaPark district. The venue is centrally located in Cologne, approximately 15 minutes by public transport from Cologne Hauptbahnhof. Cologne is served by Cologne/Bonn Airport (CGN) and has direct ICE train connections to Frankfurt (approximately 1 hour), Berlin (approximately 4.5 hours) and Amsterdam (approximately 2.5 hours).
data2day is jointly organised by Rheinwerk Verlag GmbH and Heise Medien GmbH & Co. KG, two major German-language technology media publishers. Rheinwerk publishes technical books across programming and data topics. Heise Medien publishes iX, c't and heise Developer. Their combined community footprint in the DACH developer market positions data2day within a broad reader and subscriber community.
