We have the attributes: {A, B, C, D}.Consider the following functional dependenciesA, B, C -> DA, C -> BB -> A, C, DA, B -> C, DA -> DFind all minimal keys.
Question
Solution 1
To find all minimal keys, we need to follow these steps:
-
Find the closure of each attribute:
- A+ = {A, B, C, D}
- B+ = {A, B, C, D}
- C+ = {C}
- D+ = {D}
-
From the above closures, we can see that only A and B can determine all other attributes. So, we need to check if any proper Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
