“When this is not explicitly defined, a user-defined data type or a column definition will use the default setting for nullability.”

“Because nullability is one of a number of attributes of any particular database field, and because dealing with changes in nullability is no different from dealing with name and data type changes, the idea of making a value type nullable in C# when it isn't nullable in the database just in case the underlying database schema changes makes little sense.”
