What are some effective techniques for data validation?

There are several techniques for data validation, including range checks, format checks, and consistency checks. Would you like to know more about any specific technique?

Can you explain range checks?

Sure! Range checks ensure that data falls within a specified range. For example, if you're validating age, you might check that it falls between 0 and 120.

What about format checks?

Format checks verify that data is in the correct format, such as ensuring email addresses contain '@' and a domain. This helps catch errors early.

How do consistency checks work?

Consistency checks compare data across different fields to ensure they make sense together. For instance, if a user is marked as 'active', their last login date should be recent.
