Aren’t these two basically the same thing?

Validity Check (Input Control)

-Compares data to existing tables or files

-Does a certain answer belong?

-Ex: # in a Y/N blank

-Ex: Is this person a customer?

Field Check (Input Control)

-Prevents invalid characters

-Prevents alphabetic letters from being entered into a SSN# field

I believe the key difference is that validity check is for tables, columns and rows input whereas a field is a string of characters. They are similar. Someone else add to the difference?

Yes, validity check also checks against a database, say if a customer has an account or not.

Field check is for typos.
