What is the significance of data validation?

The significance of data validation lies in its ability to ensure that the data being processed is accurate, complete, and secure. This process involves checking the integrity of data before it is used in applications or databases. By implementing data validation, developers can prevent errors that may arise from incorrect user input, such as invalid formats, out-of-range values, or missing information. This not only enhances the quality of the data but also promotes the reliability of the system as a whole.

Ensuring that data is secure is also critical, as it protects against vulnerabilities and potential breaches that could compromise sensitive information. Overall, data validation plays a fundamental role in maintaining the integrity of a system, directly influencing performance and outcomes.
