The join index JOIN the two tables together and keeps the result set in the permanent space of Teradata. This JOIN index will hold the result set of the two table, and at the time of JOIN parsing engine will decide whether it is fast to build the result set from the actual BASE tables or the JOIN index.

What you will learn

User never directly query the JOIN index. In the sense JOIN index is the result of joining two tables together so that parsing engine always decide to take the result set from this JOIN index instead of going and doing manual join on the base table.
