Can you explain the differences between INNER JOIN, LEFT JOIN, and RIGHT JOIN in SQL and how they can impact data retrieval in a secure database environment?

COVER // CAN YOU EXPLAIN THE DIFFERENCES BETWEEN INNER JOIN, LEFT JOIN, AND RIGHT JOIN IN SQL AND HOW THEY CAN IMPACT DATA RETRIEVAL IN A SECURE DATABASE ENVIRONMENT?

An INNER JOIN combines rows from two tables where there is a match in both tables. A LEFT JOIN retrieves all rows from the left table and the matched rows from the right table, returning NULL for unmatched rows. A RIGHT JOIN does the opposite, retrieving all rows from the right table and matched rows from the left table.
