Difference between LEFT OUTER JOIN and RIGHT OUTER JOIN

In left outer join tuples from the left-hand-side relation which do not match any tuple in the right-hand-side relation are padded along with nulls and are added to the result of the left outer join. Likewise, in right outer join tuples from the right-hand-side relation which do not match any tuple in the left-hand-side relation are padded along with nulls and are added to the result of the left outer join.
