R and Python Support in Teradata Vantage

Teradata Vantage supports R and Python languages both at client side and in database.

The client side and in-database options for R and Python enable users to jointly perform analytics with no SQL coding required, provide users with functions for data manipulation and transformation, data filtering and sub-setting, and can be used in conjunction with open source libraries.

Client Side

The Teradata packages for R and Python include access to powerful Vantage analytic functions together with data manipulation functions to provide extensive analytic capabilities at client side. They combine the benefits of the open source language environment with the massive parallel processing capabilities of Vantage, which includes Machine Learning Engine analytic functions and Advanced SQL Engine in-database analytic functions.

The language interpreters are installed on a client machine that connects to Vantage.
