The uncertainty associated to stored information can be put in direct correspondence to the extent to which these data violate conditions expressed as semantic integrity constraints. Thus, imposing and checking such constraints provides a better control over uncertain data. We present and discuss a condition which ensures the violation tolerance of methods for integrity checking. Usually, such ...
