Question

Based on the ERD below, display all fields in the JOB table sorted by the largest hourly charges for the job first.

The image depicts an Entity-Relationship Diagram (ERD) that showcases the relationships between four tables: JOB, EMPLOYEE, ASSIGNMENT, and PROJECT. Each table contains attributes, some of which serve as primary or foreign keys, establishing connections between the tables.

### Tables and Attributes:

1. **JOB Table**
   - **Primary Key:** `JOB_CODE`
   - **Attributes:**
     - `JOB_DESCRIPTION`
     - `JOB_CHG_HOUR`
     - `JOB_LAST_UPDATE`

2. **EMPLOYEE Table**
   - **Primary Key:** `EMP_NUM`
   - **Attributes:**
     - `EMP_LNAME`
     - `EMP_FNAME`
     - `EMP_INITIAL`
     - `EMP_HIREDATE`
     - `JOB_CODE` (Foreign Key)
     - `EMP_YEARS`

3. **ASSIGNMENT Table**
   - **Primary Key:** `ASSIGN_NUM`
   - **Attributes:**
     - `ASSIGN_DATE`
     - `PROJ_NUM` (Foreign Key)
     - `EMP_NUM` (Foreign Key)
     - `ASSIGN_JOB`
     - `ASSIGN_CHG_HR`
     - `ASSIGN_HOURS`
     - `ASSIGN_CHARGE`

4. **PROJECT Table**
   - **Primary Key:** `PROJ_NUM`
   - **Attributes:**
     - `PROJ_NAME`
     - `PROJ_VALUE`
     - `PROJ_BALANCE`
     - `EMP_NUM` (Foreign Key)

### Relationships:

- The `JOB` table is related to the `EMPLOYEE` table via the `JOB_CODE`. The cardinality indicates a one-to-many relationship, meaning a single job can be associated with multiple employees.

- The `ASSIGNMENT` table acts as a junction between the `EMPLOYEE` and `PROJECT` tables using foreign keys `EMP_NUM` and `PROJ_NUM`, indicating that multiple employees can be assigned to multiple projects. The relationships are many-to-one, denoting that each assignment is linked to one employee and one project.

This diagram is essential for understanding how different entities within a company interact and can be used to effectively manage workforce allocations and project assignments.
