Joins are used to join the datasets horizontally.
There are 2 types of joins: inner and outer joins.Outer joins includes left,right and full join.
Inner Join gives the matching records which are present in both the datasets.
Left join gives all the records that are present in left
dataset and matching records in right dataset.
Right join gives all the records in the right dataset and matching records in left datasets
full join gives all matching and non matching records found in both the datasets.
