Data validation ensures that only valid data is entered, helping to improve the accuracy and reliability of the data in a database. It helps to prevent errors and inconsistencies, and can be essential for ensuring the quality of data. While it may make data entry slightly more difficult for the user, this is a small price to pay for improved data quality. Data validation is also important for relational databases, as it helps to ensure the integrity of the relationships between different tables and fields. Data does not need to be entered twice for validation, although some systems may use this approach as a way of ensuring accuracy.
