Simple joins gives only matching/common values from two or
more tables
If you have mentioned only Outer joins then it is same as
simple join gives the matching values from two or more
tables but outer joins are of two types--- right outer join
and left outer join
for right outer join--- it will give non matching rows also
from right table in addition to matching rows
for left outer join-- it will give non matching rows also
from left table in addtion to matching rows
