For this you can make any field non nullable and offer a default value for the field.
Counter example: SAP HANA doesn't support NULLs, and as a result if I see 0 in any column in the database I have to wonder was it 0 that user submitted or 0 that system added as a placeholder. I would need to go back to documentation and see if the field is mandatory etc. Better have it explicitly stored in the data itself.
