Support nullable-types Flexberry ORM and .NET
Nullable types are an extension to the usual types that can store the value
null (that is unlike the standard types, Nullable types allow the user to store any value in a field of scalar type).
Note: When designing information systems it is necessary to consider the difference between scalar and nullable types, choosing the more suitable for a particular situation type.
