Join indexes are similar to base tables in that they support a primary index, which can be used for direct access to one or a few rows.

A single-table JI is a an index structure that contains rows from only a single-table. This type of structure has been found to be very useful by Teradata Database users because it provides an alternative approach (primary index) to directly accessing data.
