Of course I am not against criticism, so if you have some remark – let
me know, but please be specific. As I wrote it seems to me that Cimode
misunderstood something in the paper.
I believe that he interchanges:
information and knowledge;
attribute and knowledge about attribute; logical sentence and factual sentence.
On the other hand I believe that Cimode has in mind “Information Principle” which one of versions is: “The entire information content of a relational database is represented in one and only one way: namely, as attribute values within tuples within relations.”
By the way I couldn’t find a definition about attribute in Relation model.
