- Review FamCation relations and determine if they are all in 3NF. If not, which relations do you need to normalize and how?What are three criteria that indicate that a surrogate key for a relation's main key should be created?DataBase Management System Determine the keys and superkeys of the relation R(ABCDEF) with FD's: (You MUST show the step-by-step of how you find superkeys and keys) ACE →D, AEF → B, CE → B, EF → D, and ABDF → E
- Set up relationships (determining foreign keys) bymapping your ER/EER to relations and showing whatare FK and PK in your relations.Explain the First Normal Form (1NF) and provide an example of how it is applied to a relational database.Describe the Second Normal Form (2NF) and give an example of how it's applied in database design.
