Data Validation Techniques

What is Data Validation Techniques?

Data validation is crucial to maintain the integrity of a web application’s database. In my experience, combining client-side and server-side validation ensures robustness. For instance, regular expressions are powerful for format validation but should be paired with server-side checks to prevent bypassing via direct API calls. Similarly, while constraints like not null are enforced at the database level, they should be complemented with user-friendly error messages to guide users. Validation libraries help maintain consistency across the application, but they should be kept up-to-date to address evolving data validation requirements and security threats.
