The research activities at the NUS Data Management Research Lab (DMRL) focus on two broad research areas:

Streaming Media: The design, implementation and evaluation of scalable real-time streaming architectures. We focus on the challenges presented in both high quality, high bandwidth media types and large-scale, distributed peer-to-peer streaming.
Web Services and Database Integration: The design and implementation of web service architectures and their integration with web sources (especially geo-spatial information) and databases.
