Teradata Geospatial Extensions: a Case Study in User-Defined Types

Many database systems are highly extensible through user-defined types (UDTs), methods (UDMs) and functions (UDFs). Database system vendors often provide UDFs to assist users with migrating from a competitor's DBMS to their own. But UDTs, UDFs and UDMs also provide domain-specific functionality, as seen in Teradata's Geospatial Extensions. Tableau offers a simple, powerful way to exploit these DBMS extensions that can enhance the analytical expressiveness of your visualizations.
