Just a quick question.
I have created a new domain model from an existing database and have noted that the nullable property of some of the items in a class do not correspond to the nullable property of the field in the database. For example, the domain model diagram for an object named SiteService has an element named Zonenumber which has the nullable metaproperty = False but in the database table which this object is mapped to, the corresponding field is nullable. The reverse is also true - not nullable field definitions in the table are nullable in the model.
Why are these two 'nullabilities' not the same?
Regards,
Jonathan
