“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⟳.”

“We know⟳ that Kotlin requires us to explicitly define⟳ references that can hold⟳ null values. Java on the other hand is much more lenient about nullability, so we may wonder⟳ how Kotlin handles types coming from Java (basically the whole Android SDK and libraries written in Java).”
