A field refers to data that is entered. Field level validation refers to built in rules for the type / range of data that is allowed to be entered in that field. For example in a typical web registration form, valication for the field "Age" would be: 1. It should be an integer (meaning a whole number) between 0 and 100. It cannot accept alphanumeric characters. 2. It should be entered and cannot be left blank - this is my example. In a different form, it is possible that the site allows age to be left blank. A field such as "Name" may have the following validations: 1. It should not be left blank 2. It should have alphabetic characters without special characters such as *, & etc 3. It should be max 40 characters in length. There could be different types of fields and the possible validations would be different for each. I have given two examples of field level validations. These validations are performed to prevent "incorrect" data from being accepted by a system/web site.

What is the difference between field level and record level validation rule?

What is field validation?
Field validation is the process of checking and ensuring that data entered into a form field meets specified requirements or constraints. This helps to maintain data accuracy and prevent errors by validating input such as format, length, and range. Field validation can provide immediate feedback to users if their input is incorrect or incomplete, improving the overall user experience.
What data validation can be used in a database?
A database is only as useful as the data it contains. Validation helps prevent invalid or inconsistent data from getting stored. At the most elementary level, it could be as simple are requiring a given element to only contain numerical data. More complex validation rules might entail a list of valid values, cross-field edits (if field A contains "xyz", then field B cannot contain "abc") and various more complex rules known as constraints (such as foreign key and NOT NULL rules.)
What are some examples of validation rules?
Validation rules limit what can go into a field. You might want to only allow values that are over 500 in a field, so the validation would be: >500 You might want dates that are before the 1st of January 2010, so that would be like this: <#01/01/2010#
What is a set of constraints or rules that help control how data is entered into a field?
