Hi and thanks for your replies,
Message for Andreas Sheriff ! : I did not understand your solution
completely but seems nice,would you please tell me more or direct me to
proper source?
And reply for Carlos: I think there is only one entity called "Form".This
is an conceptual modeling(not design) so there is no *Entity* called filed.
You can say that I map the original ER to a logial design with two tables
named by: Form and Filed. But this has the same problem with EAV method that
I have mentioned in original post.
-Thanks
