Assume we have a relation schema R(SSN, Name, Address, LicensePlate, Make, Model).

We expect the following functional dependencies to hold:

SSN -> Name, Address

LicensePlate -> Make, Model, SSN

1. Show which attributes can be used as keys?

2. Show that the relation R is not in 2 NF

3. Propose and show a decomposition in 3NF

(Note: All three parts are the of the same question. Please do not copy/paste from other Chegg answers. Thanks.) DO NOT OR BE REPORTED.
