Abstract
Originally, database repairs were introduced with the purpose of characterizing the consistent data in apossibly inconsistent database, as the data that are invariant under the possible repairs [Arenas et al., 1999]. Along the way, repairs got a life of their own, and they started to be investigated independently from the intrinsically consistent data in a database: A repair D’ can be seen as a natural and alternative “clean” version of the original instance D. In this case, cleaning means getting rid of semantic violations while staying as close as possible to D.
