Die Untersuchung vieler aktueller Fragestellungen der Naturwissenschaften basiert auf der Auswertung großer Datenbestände mit automatischen Analysewerkzeugen, deren Zusammenspiel in sogenannten Datenanalyseworkflows festgelegt wird. Der dafür notwendige Entwicklungsaufwand ist nach wie vor sehr hoch. Der SFB “FONDA – Grundlagen von Workflows für die Analyse großer naturwissenschaftlicher Daten” (Sprecher: Prof. Dr. Ulf Leser) will diese Lücke schließen und Techniken, Verfahren und Werkzeuge erforschen, die eine Steigerung der Produktivität von Wissenschaftlerinnen und Wissenschaftlern bei der Erstellung und Anwendung von Datenanalyseworkflows ermöglichen. Er konzentriert sich dabei auf die für dieses Ziel wichtigen Eigenschaften der Portierbarkeit, Adaptivität und Zuverlässigkeit.
