SQL is the American National Standards Institute (ANSI) and International Organization for Standardization (ISO) language for relational database management. All application programming facilities ultimately make queries against Vantage using SQL.
Vantage conforms closely to the ANSI/ISO SQL standard while also supporting unique extensions that enable users to take full advantage of the efficiency of Teradata parallelism. This comprehensive language is called Teradata SQL. You can run transactions in either Teradata or ANSI mode.
