A Chen ERD notation model is used worldwide where one wishes to learn more about database and software design. The ER model is constructed using a realistic view of how the real world comprises entities and the relationships between these identified entities. A Chen’s Human Resource Database model can depict any employee’s attributes like the job history or payslip management in detail.
