Joins are used in queries to explain how different tables are related. Joins also let you select data from a table depending upon data from another table.
Types of joins:
-INNER JOIN
-OUTER JOIN (OUTER JOIN is further classified as LEFT OUTER JOINS, RIGHT OUTER JOINS and FULL OUTER JOINS)
-CROSS JOINs
