Question

I have to put the table in the attached image in 2NF and 3NF form, but am stuck. Thanks for your help.

### Data Table Description

The table provides information on employees, including their job assignments and location details. It consists of the following columns:

- **EMPLOYEE_ID**: A unique identifier for each employee (e.g., E001, E002, E003).
- **NAME**: The name of the employee (e.g., Alice, Bob).
- **JOB_CODE**: A unique code representing a specific job role (e.g., J01, J02, J03).
- **JOB**: The job title associated with the job code (e.g., Chef, Waiter, Bartender).
- **STATE_CODE**: A numerical representation of the employee's home state (e.g., 26 for Michigan, 56 for Wyoming).
- **HOME_STATE**: The name of the employee's home state (e.g., Michigan, Wyoming).

### Data Entries

- Employee E001 (Alice) has a Chef position (J01) in Michigan and a Waiter position (J02) also in Michigan.
- Employee E002 (Bob) works as a Waiter (J02) and a Bartender (J03) in Wyoming.
- Alice (E003) is recorded again as a Chef (J01) but associated with Wyoming this time.

### Questions for Analysis

4. Is this data already in 1NF? If so, what field(s) make up the primary key?
5. Construct a dependency diagram that meets the 1NF standard.
6. Refine the design further to meet 2NF standards.
7. Make a final revision that adheres to 3NF.

This table is useful for understanding basic database normalization concepts and how to transition data through various normal forms to eliminate redundancy and improve data integrity.
