Some of you may be familiar with relational databases other than Teradata and how those other RDBMs utilize indexes. In Teradata, an âIndexâ 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.
Teradata systems were the first to store and analyze 1 terabyte of data in 1992. Hard disk drives were 2.5GB in 1991 so the definition of big data continuously evolves according to Kryder's Law. Teradata installed the first petabyte class RDBMS based system in 2007.
