| Question 115 |
From the following instance of a relation scheme R(A,B,C), we can conclude that:
| A functionally determines B and B functionally determines C | |
| A functionally determines B and B does not functionally determines C | |
| B does not functionally determines C | |
| A does not functionally determines B and B does not functionally determines C |
Question 115 Explanation:
From the given instance of relation it can be seen that A functionally determines B, but we cannot conclude this for the entire relation.
But for the given instance it can be seen that B does not functionally determines C, and it can be concluded for entire relation.
But for the given instance it can be seen that B does not functionally determines C, and it can be concluded for entire relation.
