What does it mean when a database field is Mandatory ?
If you define a database field as Mandatory, it cannot contain an
unknown value (?). However, it can have a space as its value.
The default value is no. If you accept no for this field, you indicate
that the unknown value is an allowed value for the field.
This information is in the Basic Development Tools Manual, Chapter 5.
