You need not directly code SQL queries to take advantage of ordered analytical functions. Both Teradata Database and many third-party query management and analytical tools have full access to the Teradata SQL ordered analytical functions. Teradata Warehouse Miner, for example, a tool that performs data mining preprocessing inside the database engine, relies on these features to perform functions in the database itself rather than requiring data extraction.

Teradata Warehouse Miner includes approximately 40 predefined data mining functions in SQL based on the Teradata SQL-specific functions. For example, the Teradata Warehouse Miner FREQ function uses the Teradata SQL-specific functions CSUM, RANK, and QUALIFY to determine frequencies.
