Data Exchange: Getting to the Core
Summary: Core of any universal solution is unique (up to isomorphism), is the minimal universal solution, and optimally answers unions of conjunctive queries with inequalities. Complexity: core computation NP-hard in general and core-recognition DP-complete; provide broad data-exchange conditions yielding polynomial-time construction.
