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…

Declarative Semantics for Active Rules

Sergio Flesca, Sergio Greco

In this paper we analyze declarative deterministic and non-deterministic semantics for active rules. In particular we consider several (partial) stable model semantics, previously…

Greedy Algorithms in Datalog

Sergio Greco, Carlo Zaniolo

In the design of algorithms, the greedy paradigm provides a powerful tool for solving efficiently classical computational problems, within the framework of procedural languages. Ho…
