How can a database be designed to reduce the likelihood of data-entry errors?

To reduce data-entry errors, a database can be designed with input validation rules, such as constraints on data types, formats, and ranges, ensuring that only valid data is accepted. Utilizing dropdown menus or predefined lists for fields like categories or statuses can further minimize mistakes. Implementing user-friendly interfaces with clear instructions and real-time feedback can also help guide users during data entry. Additionally, employing regular audits and error-checking routines can help identify and correct inaccuracies promptly.
