The topics under joins are not yet covered in our series.

Cartesian Join (Cross Join):A Cartesian join returns the Cartesian product of the two tables involved.It combines every row of the first table with every row of the second table, resulting in a potentially large number of rows in the output.There is no specific condition used to join the tables; instead, it generates a row for every possible combination of rows from the two tables.It is used when you want to generate all possible combinations between two tables.

Inner Join:An inner join returns only the rows from both tables that satisfy the join condition.It selects only the rows from both tables where the join condition evaluates to true.Inner join is the most common type of join and is used to retrieve rows that have matching values in both tables.The join condition typically involves comparing the values of one or more columns from each table.
