Description: A validation error occurs when input data does not meet specified criteria. This type of error is fundamental in software development, as it ensures that processed information is correct and in the expected format. Data validation is a critical step in most applications, as it helps prevent security issues, such as code injections, and ensures that data is consistent and useful. Validation errors can arise at various stages of the software lifecycle, from user input in forms to interaction with databases and APIs. In many development environments, validation is implemented to ensure that user-entered data is valid before being processed. This not only enhances the user experience by providing immediate feedback but also protects the integrity of the system. Proper management of these errors is essential for developing robust and secure applications, and handling them can include everything from clear error messages to implementing automatic correction logic.
