Processing Queries in a Large Peer-to-Peer System (2003)
Leonidas Galanis, Yuan Wang, Shawn R. Jeffery, David J. Dewitt
Abstract. While current search engines seem to easily handle the size of the data available on the Internet, they cannot provide fresh results. The most up-to-date data always resides on the data...
Locating data sources in large distributed systems (2003)
Leonidas Galanis, Yuan Wang, Shawn R. Jeffery, David J. Dewitt
Querying large numbers of data sources is gaining importance due to increasing numbers of independent data providers. One of the key challenges is executing queries on all relevant information...
