Naming of boolean column in database table

Question

I have 'Service' table and the following column description as below

1. Is User Verification Required for service ?
2. Is User's Email Activation Required for the service ?
3. Is User's Mobile Activation required for the service ?

I Hesitate in naming these columns as below

IsVerificationRequired IsEmailActivationRequired IsMobileActivationRequired 

or

RequireVerification RequireEmailActivation RequireMobileActivation 

I can't determined which way is the best .So, Is one of the above suggested name is the best or is there other better ones ?

Answer 1

I would (and do) use "IsVerificationRequired"

I try to add some meaning to my column names so it's obvious (ValueDate, InsertedDateTime, IsActive, HazCheezBurger, ProductName etc). "Isxxxx" implies yes/no for example without thinking and you only have 2 states unlike "ProductName".

Answer 2

Run with the Is variants, or at the very least swap the Require to Requires. Booleans should be phrased as questions. Is, Can, Has, Should, they're all good prefixes for Boolean functions/columns. See 1370840 for more arguments on this
