Question

in Python

Project 5: Payroll (Part 1) CS 1410 Background In this project you will implement a simple payroll system. For the first part of the assignment, you will submit a UML class diagram. The hypothetical company we are considering has 3 classifications of employees: 1. Hourly 2. Salaried 3. Commissioned There are 24 pay periods per year; 1/24th of a salary is paid each pay period to employees who receive a salary. We won't worry about taxes and other deductions for this assignment. Hourly employees are simply paid their hourly rate times their hours worked for that pay period. We won't worry about overtime. Salaried employees are simply paid 1/24 of their salary. Commissioned employees are Salaried employees, but also receive an additional payment of their total sales times their commission rate. Employees can have their classifications changed during their employment. Payment is distributed in two ways: 1. Direct transfer to a bank account 2. Receiving a check by mail Employees can change their desired payment method at any time. We will simulate issuing payment by just writing text to a file. The important part of this project is the object-oriented design. You will do this assignment in two parts: 1. Submit a UML class design document for your classes. 2. For Part 2, submit a source file, payroll.py, with your implementation Requirements (Part 1) Employee objects have the following required attributes: • emp_id: string • name: string • address: string
