ER diagram for the HR database using boxes (for entities) and lines (for relationships):


1. Employees belong to a Department (One-to-Many)
2. Each Employee is assigned a Job (Many-to-One)
3. Jobs have an associated Salary Range (One-to-One)
4. Departments are located in a Location (Many-to-One)

This text-based diagram uses simple boxes and connecting lines to visually represent the key entities and their relationships.
