Consistency Checking and Querying in Probabilistic Databases under Integrity Constraints
Sergio Flesca, Filippo Furfaro, Francesco Parisi
We address the issue of incorporating a particular yet expressive form of integrity constraints (namely, denial constraints) into probabilistic databases. To this aim, we move away…
Consistent query answers on numerical databases under aggregate constraints
Sergio Flesca, Filippo Furfaro, Francesco Parisi
The problem of extracting consistent information from relational databases violating integrity constraints on numerical data is addressed. In particular, aggregate constraints defi…
Estimating Range Queries using Aggregate Data with Integrity Constraints: a Probabilistic Approach
Francesco Buccafurri, Filippo Furfaro, Domenico Sacca'
The problem of recovering (count and sum) range queries over multidimensional data only on the basis of aggregate information on such data is addressed. This problem can be formali…
