Enterprises often need to assess and manage the risk arising from uncertainty in their data. Such uncertainty is typically modeled as a
probability distribution
over the
uncertain data
values, specified by means of a complex (often predictive) stochastic model. The
probability distribution
over data values leads to a probability dis- tribution over
database query
results, and
risk assessment
amounts to exploration of the upper or lower tail of a query-result distribu- tion. In this paper, we extend the
Monte Carlo
Database System
to efficiently obtain a set of samples from the tail of a query-result distribution by adapting recent "Gibbs cloning" ideas from the sim- ulation literature to a database setting.
