Hi !



Since this is a database theory group and  I'm bored by the null and 3vl
threads I ask yet another elementary question:



Suppose you have this relation R(A,B,C) with the following functional
dependencies AB->C and C->B.


What is the best way to implement this in available SQL DBMS in your opinion
?



Regards,


x
