Abstract | An Abductive method for checking integrity constraints in relational databases is proposed by extending the simplification method. The simplified form of the integrity constraints computed by the method can be evaluated before the actual update is performed. An update is regarded as an action performed on a database state. The effects of updates on the database state and the integrity constraints are represented in logic program. The simplified form of integrity constraint is derived by using SLD-NF, partial evaluation and abduction. The soundness and completeness of evaluating the simplified integrity constraints in the initial state, to ensure that the integrity constraints are satisfied in the new state after the update, is established. |
