The UML class diagram for the employee payroll system shows how the system interacts with various classes such as admins, employees, departments, leave, payroll, and tax. Each class has attributes like employee ID, payroll ID, tax ID, and methods like calculate salary(), approve leave(), and view Pay slip().
Here admins take care of department and employee records. The UML class diagram helps to appreciate the design of the system in the context of how the payroll, leave, and tax computations are interconnected within the system.
