SpADE: A SPatio-temporal Autonomic Database Engine for location-aware services (funded by A*STAR 2003-2007) Adaptive B+-tree based indexes and query processing strategies have been designed and incorporated into MySQL, which acts as the database engine. UTab: A Universal Table inspired storage system for free-and-easy data publishing and sharing. 2005-- (funded by MOE Singapore) BestPeer 2.0: a peer-to-peer based data management system which supports both structured (BATON)[VLDB2005, SIGMOD2006] and unstructured with supernodes overlays. It is a one-platform multi-structures p2p network that is able to support expansion-based routing in unstructured setting, and DHT-based exact and range-based routing in structured setting. It supports keyword, similarity and attribute based query retrieval. It is designed to provide enterprise-quality data processing capability in corporate networks. It uses JIT and approximate indexing to reduce maintenance cost. The system is built in lego block manner, and each main concept/component is tested on PlanetLab before it is incorporated into BestPeer.
