HR-Employee-Management. The aim of this code is to compare and identify the changes between two worksheets that contain yearly employee data. We focused on what we deemed as the most important changes (variables) contained in a company’s employee data set. These variables are: employee id (primary key), name, designation of employee, salary and location. The code aims at identifying the new, ex-employees and the employees that stayed in the company. Additionally, the code is designed to display qualitative (e.g. changes in employee designation) as well as quantitative differences (salary changes). This will serve as a useful tool for HR managers (end-users).
