  • Task 1: Create 3 rows of data for each table ensuring that the referential integrity is valid.
  • Task 2: Create a SELECT query for every table that displays all the columns and shows all three rows. Take a screen shot that shows each query and its output.
  • Task 3: Write SELECT statements for the following (include a screenshot of the SQL and its execution, including the resulting data):
    • Display the employee id, contact id, first_name, middle name, last_name, and phone number for all employees.
      • Rows returned
