Joins are used to extract data from more than one DB table
which are logically related to each other.
So in order to join DB Tables they should have a common
field or attribute.
In ABAP, We have two types of Joins.
1) Inner Joins
2) Outer Joins ( Left Outer and Right Outer)

Inner Joins retrieve the records which matched with join
condition only.
While outer joins Retrieve the records which are matched
with Join Condition and Remaining records from the Parent Table.
