  • Tajo: A Distributed Data Warehouse System on Large Cluster

    Tajo is a relational and distributed data warehouse system for Hadoop. Tajo is designed for low-latency and scalable ad-hoc queries, online aggregation and ETL on large-data sets by leveraging advanced database techniques. It supports SQL standards. Tajo uses HDFS as a primary storage layer and has its own query engine which allows direct control of distributed execution and data flow. As a result, Tajo has a variety of query evaluation strategies and more optimization opportunities.

  • GraphMR: A Distributed Graph Match Method using MapReduce

    This work is a distributed graph match method on large data sets. This work was submitted to IEEE Transactions on Kowledge and Data Engineering (TKDE).

  • SPIDER: A System for Scalable, Parallel / Distributed Evaluation of large-scale RDF

    This project aims at processing large-scale RDF data. In this project, we developed scale RDF processing method using MapReduce that is a distributed processing framework and storing techniques for large RDF data sets. This project was demonstrated in the 18th ACM Conference on Information and Knowledge Management (CIKM) in November 2009.

  • R3 - Wireless Broadcast System

    This is a system that consist of server and client. The server broadcast news data and the client can connect to the channel and get the data.
