Input data validation is the process of checking user input for errors or unreasonable values before the data is processed or stored. This helps to prevent errors and ensure data integrity. Relational data validation is concerned with ensuring that data relationships are consistent and correctly established, while arithmetic data validation checks the results of calculations for errors. Output data validation involves checking the results of processing to ensure that they are correct and consistent with expectations. However, none of these options are specifically related to checking user input data for errors. Input data validation checks user input data for errors like incorrect format or unreasonable values before it is processed. This ensures that the data entered is valid and reliable for further use. Relational data validation is concerned with ensuring that data in a database is consistent and correct. Arithmetic data validation involves checking mathematical operations for correctness. Output data validation is concerned with ensuring that the output of a system meets the necessary requirements.
