— A paramount challenge in probabilistic databases is the scalable computation of confidences of tuples in query results. This paper introduces an efficient secondary-storage o...
Testing an SQL database system by running large sets of deterministic or stochastic SQL statements is common practice in commercial database development. However, code defects oft...
Query optimizers in current database systems are designed to pick a single efficient plan for a given query based on current statistical properties of the data. However, different...
