You didnt understand my point. Design classes coupled with DB framework is
not a solution.
In the following class
type
TPerson = class(TObject)
private
FId: Integer;
FName: String;
FBirthDate: TDateTime;
public
property Id: Integer read FId write FId;
property Name: String read FName write FName;
property BirthDate: TDateTime read FBirthDate write FBirthDate;
end;
Suppose that this class represent data of the Person table in a sql
database. Suppose that there is records where the column "BirthDate" is
null. How do i represent a null "BirthDate" in my object?
