An illustration of a one$-$to$-$many relationship would be:

an employee listed in the Employees table earns a raise, so the Salaries table must be updated.

an employee leaves the company so that when he is deleted from the Employees table, his salary data will be deleted from the Salaries table.

a customer may have more than one account in an accounts table.

each employee in an Employees table has a matching entry in the Salaries table.
