Welcome to the home of Data
Management Group at the Computer
Science
Department of Brown University.
We have been leaders in object-oriented database systems and advanced query languages and query processing. We have a strong interest in data management for networked systems, including the intelligent use of resources for broadcast and dissemination-based systems. We focus on the emerging area of data-stream management systems (DSMS) with an emphasis on real-time processing, quality of service maintenance, and approximate answers. Our work also includes content-based data access in wireless and ad hoc networks.
