Finding Employees with the Highest Salary in Each Department

Use a subquery to find the maximum salary for each department by grouping the Employee table by departmentId and selecting the maximum salary.
Join the Employee table with the Department table to get the department names along with the employee details.
Use a WHERE clause to filter the joined result, keeping only the rows where the employee's salary and department match the maximum salary found in the subquery.
Select the required columns (Department.name, Employee.name, and Employee.salary) to form the final result set.
