Identify all partial dependencies and transitive dependencies.
(Note: Primary keys are identified as TRIP-CODE)
You can notate each dependency using text presentation as seen in the following example: (assuming that A, B, C, D, E, and F are attribute names)
- partial dependency: A --> B, C
- transitive dependency: D --> E, F
