3. Now, perform joins between the Department and Employee tables and show
results for how many employees work in each one of the four departments. This will
only provide information on the records that are already there.

a. Department 1 = Accounting

i. Command: SELECT First_Name, Last_Name,
Department.Department_Name FROM Employee INNER JOIN
Department ON Employee.Department_ID = Department.Department_ID
WHERE Employee.Department_ID = 1;
b. Using SELECT statements similar to the one above, perform joins to produce
results for the following tables:

i. Department 2 = Human Resources
ii. Department 3 = Information Systems
iii. Department 4 = Marketing
c. Capture the results of these joins and validate your work by providing a
screenshot. You should have the same number of records as you do employees.
