What are some effective methods for data validation?

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

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 an email address contains an '@' symbol or that a phone number has the right number of digits.

How do consistency checks work?

Consistency checks compare data across different fields to ensure they make sense together. For instance, if a user’s start date is after their end date, that would be flagged as inconsistent.
