Database research at the National University of Singapore

At the National University of Singapore (NUS), the database group has worked on a wide range of research, ranging from traditional database technology (e.g., database design, query processing and optimization) to more advanced database technology (e.g., cloud and big data management) to novel database utilities (e.g., database usability, visualization, security and privacy). In this article, we describe some recent and on-going interdisciplinary projects for which we have received significant amount of funding.
