Welcome to the Home of the Penn Database Group!

As one of the top database research groups in the world, the Penn Database Group has made many fundamental contributions to the field — particularly in areas relating to scientific data management, Web data management, distributed data sharing, data provenance, and machine learning systems. Our research spans from theory to systems, AI, and applications, and it connects to other research areas within Penn’s CIS Department (such as machine learningprogramming languageslogic and computation, computer networks, distributed systems, and approximation algorithms). Within the University, we also collaborate frequently with the Institute for Biomedical Informatics, the Center for Neuroengineering and Therapeutics, the ASSET Center, and the Warren Center for Network and Data Science. Our alumni are faculty in universities like U Washington, U Edinburgh, Duke U, IIS-Bangalore, and more; researchers with companies like Facebook-Meta, Amazon Web Services, and Google; and engineers all across tech.
