The DBO Database System (598)

By Florin Rusu, Fei Xu, Ravi Jampani, Luis Perez, Mingxi Wu, Chris Jermaine and Alin Dobra


We demonstrate our prototype of the DBO database system. DBO is designed to facilitate scalable analytic processing over large data archives. DBO’s analytic processing performance is competitive with other database systems; however, unlike any other existing research or industrial system, DBO maintains a statistically meaningful guess to the final answer to a query from start to finish during query processing. This guess may be quite accurate after only a few seconds or minutes, while answering a query exactly may take hours. This can result in significant savings in both user and computer time, since a user can abort a query as soon as he or she is happy with the guess ’ accuracy. 1
