The Recovery of a Schema Mapping: Bringing Exchanged Data Back

Summary: Define recovery: a reverse mapping M' that soundly reconstructs source data and an order on recoveries to single out maximum recoveries. Give necessary-and-sufficient existence conditions, show FO-to-CQ s→t deps admit maximum recoveries, provide exp-time (quadratic for full) algorithms, characterize expressiveness and analyze complexity vs. inverses.
