Thank you Roy. I think almost the same.



But I'm sure that name is not only psychological issue. Just one example (no RM in the one).



I can write X+Y to sum two values. But in modern programm languages I can use very complex names to denote the values. These names are full of meaning, but they are not only psychology, because system translates them into set of operation to obtain the denoted values from memory.



I think that the same process is possible for relations too. Just imagine - a system can analyzes complex names (I write about) and calculate the virtual relation from real relations according to the given complex names and some predefined rules. (Of course the system uses relational operation only in all the calculations.) In this case it's not necessary to define the calculation expression by hand. Only complex names have to be given which correspond to predefined rules.  If I use other combination of name I'll get other result. So the rules are equal to definitions of many virtual relation. In this case complex names are full of meaning and also are used by system to obtain denoted relations.



My question again :) Is this system relational?
