Teradata

Teradata is a database management system (DBMS) created by NCR Corporation. It consists of both custom hardware and custom software. The main point with the Teradata DBMS is that it can handle more than 1 terabyte of data, which is why it is used a lot in very large scale data warehousing applications.

Teradata runs its own operating system, NCR UNIX SVR4 MP-RAS[?], a variant of System V UNIX from AT&T.

Teradata DBMS often stand by themselves and are used through ODBC by applications typically running on a different operating system such as Microsoft Windows or other flavors of UNIX.

The first and foremost customer of this DBMS is Wal-Mart, who run their central inventory and other financial systems on Teradata.

The main competitors are other high-end vendors such as IBM and Oracle.
