N2 - This paper addresses the problem of managing inconsistent databases, that is, databases violating integrity constraints. Different approaches for repairing and querying inconsistent databases in the presence of full integrity constraints are discussed. Particular settings where restricted classes of constraints (tuple and equality generating dependencies) and particular repair strategies, based on insertion, deletion and update operations, are considered. Moreover, the problem of computing consistent query answers under different repair strategies is analyzed.
