Current system projects:

Best Peer

BestPeer is a peer-to-peer based data management system which supports both structured (BATON) and unstructured with suppernodes 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.

S3

This project aims to build a Scalable, Shareabe and Secure P2P based data management system. It is built on BestPeer project and funded by A* STAR.

SpADE

SpADE is a SpAtio-temporal Database Engine for managing moving objects. The objective of the project is to provide effective and efficient database support for Location-Based Services (LBS).

This project is funded by A* STAR.

UTab

The primary goal of this project is to build a Universal TABle storage system for managing data on small devices, P2P nodes, and community web management systems (CWMS). We are studying novel techniques for fast and layman-proof insertion of tuples into genetic tables, efficient indexing, semantics resolving and efficient query processing.

PIPA

In the PIPA project, we aim to build a database system for storage and manipulation of interactive media, video, audio, and image data. The interesting research issues we try to solve in this project include 1) efficient indexing techniques for interactive media; 2) storage methodology for smart media objects; 3) novel interface paradigm; 4) effective distance/similarity methods for matching multimedia objects; and 5) efficient query processing.
