- finding candidate keys
- Relevant Equations
- none
These are the FDs:
AB=>CD
C=>A
D=>B
My method of finding candidate keys is:
1) Look at RHS
2) Whatever isn't there could be a candidate key. (Find its closure).
But here everything is in RHS. So, I'm confused.
Can you share a better method to find candidate keys without getting too verbose(DBMS is too verbose).
