Uniform Operational Consistent Query Answering

Summary: Introduces uniform operational CQA: a probabilistic operational-repair framework that assigns uniform distributions over repairs, operation sequences, or step-wise choices to compute consistent-answer probabilities via randomized iterative repairs. Performs a fine-grained data-complexity study for conjunctive queries under functional dependencies, giving exact/approximate complexity results and showing existence of efficient approximation schemes beyond classical primary-key limits.
