Abstract
repAIrC
, a prototype implementation of the algorithms previously proposed targetting SQL databases, i.e., the most prolific type of databases. Using repAIrC
, we can both validate an SQL database with respect to a given set of AICs and compute possible repairs in case the database is inconsistent; the tool is able to work with the different kinds of repairs that have been considered, and achieves optimal asymptotic complexity in their computation. It also implements strategies for parallelizing the search for repairs, which in many cases can make untractable problems become easily solvable.
