[edit] Technology
Teradata is a massively parallel processing system running a shared nothing architecture. The Teradata DBMS claims to be linearly and predictably scalable in all dimensions of a database system workload (data volume, breadth, number of users, complexity of queries), although in practice there are limitations and non-linearities to the absolute scalability. 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 Engenio or EMC disk arrays for database storage.
[edit] Operating System Compatibility
Teradata offers a choice of several operating systems:
- NCR UNIX SVR4 MP-RAS, a variant of System V UNIX from AT&T
- Microsoft Windows 2000 and Windows Server 2003
- SUSE Linux on 64-bit Intel servers.
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.
[edit] Customers
Teradata 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 is generally regarded by the DBS industry as being the largest data warehouse in the world. Other Teradata customers include companies like AT&T (formerly SBC), Dell, Continental Airlines, FedEx, Vodafone, Best Buy, T-Mobile, and USPS.
[edit] Competition
Teradata's main competitors are other high-end solutions from vendors such as Oracle, IBM, and Sybase. Recent competition has arisen from data warehouse appliance vendors such as Netezza and DATAllegro that use similar shared nothing architectures, and packaged data warehouse applications such as SAP and Kalido have slowed Teradata's penetration into the mid-market and some verticals, particularly energy.

The founding "Group of Six" from 1979:
- Dr. Jack E. Shemer, President and Chairman of the Board.
- Dr. Philip M. Neches, Vice President and Chief Scientist
- Walter E. Muir, Vice President of Marketing
- Jerold R. Modes, Vice President and Chief Financial Officer
- William P. Worth, Vice President of Manufacturing
- Carroll Reed, Vice President of Research and Development
1976-1979 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 revolutionary database management system for parallel processing with multiple microprocessors, specifically for decision support.
1979 Teradata was incorporated on July 13, 1979, and started in a garage in Brentwood, Calif. The name Teradata symbolized the ability to manage terabytes (trillions of bytes) of data. The founders and venture capital companies bet on parallelism, relational databases, and Intel-based server clusters. At the time, all three were new, high risk technologies.
1983 The first beta system was shipped to Wells Fargo Bank.
1984 World’s first Production implementations of parallel RDBMS for decision support.[citation needed]
1986 FORTUNE Magazine named Teradata “Product of the Year.”
1987 Teradata IPO in August.World’s first cost-based parallel optimizer for decision support installed.Teradata channel connects the DBC/1012 to IBM MVS mainframes.
1989 Teradata channel connects the DBC/1012 to Univac OS1100 mainframes.
1990 The first system over one terabyte (a trillion bytes) went live. Teradata acquires Sharebase (formerly Britton Lee) database computer company. Teradata Corporation partnered with NCR Corporation to build the next generation of database computers.
1991 In December, NCR announced its acquisition of Teradata.
1992 The first system over three terabytes (a trillion bytes) went live.
1994 Gartner named Teradata the “Leader in Commercial Parallel Processing.”
1995 IDC consulting group named Teradata number one in MPP (massively parallel processing) in Computerworld Magazine.
1996 A Teradata Database was the world’s largest database with 11 terabytes (11 trillion bytes) of data. Gartner commented “... NCR’s Teradata V2 has proven it can scale...” And the Data Warehouse Institute presented Teradata with its Best Practices Award in data warehousing. Teradata introduces Teradata Customer Relationship Management (CRM), a software application and one of Teradata’s first packaged enterprise analytic solutions.
1997 Teradata ships “virtual AMPs”. Following a server node failure, the virtual AMP migrates to other hardware server nodes, one of the earliest known commercial examples of grid computing.
1998 Teradata was ported to Microsoft Windows NT.
1999 The database of one of Teradata’s customers was the world’s largest database in production with 130 terabytes (130 trillion bytes) of user data on 176 nodes.[citation needed]
2000 Launched analytical solutions - Value Analyzer and Demand Chain Management.
2001 Teradata more than doubled the lines of code (1.6 million to 3.8 million).[citation needed] Introduces Teradata CRM Version 4.0, fully integrating all previous Teradata CRM functionality into an application acquired from Ceres, Inc. in 2000.
2001 Teradata bought a research center, The Center for Customer Relationship Management, at Duke University's Fuqua School of Business.
2002 Teradata launched Teradata Warehouse 7.0 and enterprise analytic solution, Supply Chain Intelligence.
2003 Teradata University Network was created to advance awareness of data warehousing in the academic community. Nearly 170 universities from 27 countries are represented in the network. Intelligent Enterprise magazine recognized Teradata as the most influential global technology vendor.
2004 Teradata and SAP, announced a technology partnership. Teradata announced the availability of Teradata Warehouse 8.0.
2005 Teradata launched Teradata Warehouse 8.1. Launched enterprise analytic solution, Finance and Performance Management.
2006 Teradata completes a Linux port and releases Teradata Warehouse 8.2. Purchased Master Data Management solution from i2.
2007 On January 8, 2007, NCR announced its intention to spin the Teradata division off to its shareholders.
