Teradata
Teradata Corporation () is a hardware and software vendor specializing in data warehousing and analytic applications. Teradata was formerly a division of NCR Corporation, the largest company in Dayton, Ohio. Teradata's headquarters are in Miamisburg, OH. The spinoff from NCR occurred on October 1, 2007.
TechnologyTeradata is a massively parallel processing system running a shared nothing architecture. The Teradata DBMS is linearly and predictably scalable in all dimensions of a database system workload (data volume, breadth, number of users, complexity of queries).[1] The scalability explains its popularity for enterprise data warehousing applications. Teradata is offered on Intel servers interconnected by the BYNET messaging fabric. Teradata systems are offered with either Teradata-branded LSI or EMC disk arrays for database storage. Operating System CompatibilityTeradata offers a choice of several operating systems:
Introduction Teradata is a software company, founded in 1979, that develops and sells a relational database management system with the same name. Teradata is a division of the NCR Corporation, which acquired the Teradata Company on February 28, 1991. However, on January 8, 2007, NCR announced that it will spin-off Teradata as an independently traded company. Teradata Enterprise Data Warehouses are often accessed via ODBC or JDBC by applications running on operating systems such as Microsoft Windows or flavors of UNIX. The warehouse typically sources data from operational systems via a combination of batch and trickle loads. Teradata acts as a single data store that can accept large numbers of concurrent requests from multiple client applications. Significant features include:
CustomersTeradata currently has over 1,000 customers and over 1,900 installations of its RDBMS. The largest and most prominent customer is Wal-Mart, which runs its central inventory, enterprise reporting, and other financial systems on Teradata. Wal-Mart's Teradata Data Warehouse was formerly the largest data warehouse in the world. (According to the Guinness Book of Records [2], as of May 2008, the largest data warehouse is a 1 Petabyte Sybase IQ. implementation). Other Teradata customers include companies such as AT&T (formerly SBC), Bank of America, Best Buy, Coca Cola, Continental Airlines and FedEx. [3] CompetitionTeradata's main competitors are other high-end solutions from vendors such as Oracle, IBM, and Sybase IQ. Recent competition has arisen from data warehouse appliance vendors such as DATAllegro, Greenplum and PANTA that use similar shared nothing architectures, and from packaged data warehouse applications such as SAP and Kalido, as well as hybrid solutions from Netezza. These have slowed Teradata's penetration into the mid-market and some verticals, particularly energy. In 2007, HP entered the data warehouse market with "Neoview", and raised some eyebrows when they announced a sale to Wal-Mart, a stalwart Teradata customer. Notable about HP's entry into this market is that HP's CEO Mark Hurd formerly led NCR's Teradata Division. HistoryTeradata was founded in 1979 by:
Between 1976 and 1979 the concept of Teradata grew out of research at the California Institute of Technology (Caltech) and from the discussions of Citibank?s advanced technology group. Founders worked to design a database management system for parallel processing with multiple microprocessors, specifically for decision support. [4] Teradata was incorporated on July 13, 1979, and started in a garage in Brentwood, Calif. The name Teradata was chosen to symbolize the ability to manage terabytes (trillions of bytes) of data. [4] A beta system was shipped to Wells Fargo Bank in 1983,[4] and a production parallel RDBMS for decision support, the world's first, appeared in 1984. FORTUNE magazine named Teradata ?Product of the Year? in 1986.[4] Over the next four years channel connections to IBM MVS[4] and Univac OS1100 mainframes were introduced, and a Teradata system over one terabyte (a trillion bytes) went live.[4] In December 1991, NCR, then a division of AT&T, acquired Teradata.[4] Teradata split from NCR and officially became Teradata Corporation (NYSE: TDC) on October 1, 2007. In 1996 a Teradata Database was the world?s largest, with 11 terabytes of data, and by 1999 the database of one of Teradata?s customers was the world?s largest database in production with 130 terabytes of user data on 176 nodes.
