Abstract |
In order to deal with data inconsistency problems in relational databases, a new method based on rough set theory which checks data consistency solely based on data is presented. The inconsistent data that exist under the attribute sets in the relations having possible functional dependencies can be found effectively by applying the suggested rough set based consistency checking method. The method is illustrated by examples. |
