A framework for computing consistent answers to boolean aggregate queries in numerical databases violating a given set of aggregate constraints is introduced. Both aggregate constraints and queries are aggregation expressions consisting of linear inequalities on aggregate-sum functions. In particular, our approach works for a specific but expressive form of aggregation expressions (called steady aggregation expressions) and computes consistent answers by solving Integer Linear Programming (ILP) problem instances.
