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
