Some of you may be familiar with relational databases other than Teradata and how those other RDBMs utilize indexes. In Teradata, an “Index” is a physical mechanism that is used to distribute, store, and access data rows. Indexes provide a physical access path to the data and their use can avoid unnecessary full-table scans to locate rows.
