Data should also be uniform and the irregularities should be eliminated in the set. Consistency should also be present that eliminates the syntactical errors in the set. Cleaning the data should also give the uniqueness of the set in order to tell the number of duplicates that were present before the cleaning. Lastly, the data should have integrity in combining the criteria of soundness and completeness. If the above criteria are met, it is ensured that the data set is in the best state.
