Challenge: Highest Paid Employee per Department
In a typical Human Resources database, you may be asked to find the highest paid employee in each department. This is a common scenario where subqueries are invaluable: you need to compare each employee’s salary within their department and return only those who earn the most. The challenge is to write a query that, for every department, identifies the top earner by salary. You have access to the departments and employees tables, where each employee is linked to a department and has a salary value. Your goal is to use subqueries to determine the highest paid employee for each department.
