Re: Possible bridges between OO programming proponents and relational model

You believe my point is to prove that memory model redefines logical model while I stated that it restricts its implementation. It is not the same thing!!.
Unless you can prove that memory model does in fact implement *physically* multidimensionality (mathematically speaking not a logical standpoint). I respectfully believe you are making the confusion.
