Teradata Corporation is a provider of database-related products and services. The company was formed in 1979 in Brentwood, California, as a collaboration between researchers at Caltech and Citibank's advanced technology group. The company was acquired by NCR Corporation in 1991, and subsequently spun-off again as an independent public company on October 1, 2007.
The company produces a relational database management system of the same name, which it markets as a data warehouse. It also acquired new technologies by making many acquisitions. In November 2015, after continued losses, the company announced a business transformation review, which led to divestitures and replacement of executives.
Teradata employed 11,300 as of December 31, 2015, and its corporate headquarters are located in Dayton, Ohio.
Teradata is an enterprise software company that develops and sells a relational database management system (RDBMS) with the same name. Teradata is publicly traded on the New York Stock Exchange (NYSE) under the stock symbol TDC.
The flagship Teradata product is referred to as a "data warehouse system" which stores and manages data. The data warehouses use a "shared nothing architecture", which means that each server node has its own memory and processing power. Adding more servers and nodes increases the amount of data that can be stored. The database software runs on the servers and spreads the workload among them. In 2010, Teradata added text analytics to track unstructured data, such as word processor documents, and semi-structured data, such as spreadsheets.
Teradata has a supplier diversity program that designates a minimum of 3 to 5% of spending on minority, women, veteran, or small business vendors. In 2013, the Ethisphere Institute named Teradata as one of the "World's Most Ethical Companies."
Teradata holds an annual user group conference and expo known as Teradata Partners with keynote industry speakers, educational sessions led by customers and other vendors. The Teradata Partners Conference has been an annual event since 1985. The conference involves lectures and speeches on technical and business topics and announcements about new products.

Technology and products
Active enterprise data warehouse
Teradata Active Enterprise Data Warehouse, often called Teradata Database, includes data management tools and data mining software. Teradata's product can be used for business analysis. Data warehouses can track company data, such as sales, customer preferences, product placement, etc.
The data warehouse differentiates between "hot and cold" data - meaning that the warehouse puts data that is not often used in a slower storage section. As of October 2010, Teradata uses Xeon 5600 processors for the server nodes.
Teradata Database 13.10 was announced in 2010 as the company's database software for storing and processing data.
Teradata Database 14 was sold as the upgrade to 13.10 in 2011 and runs multiple data warehouse workloads at the same time. It includes column-store analyses.
Teradata Integrated Analytics is a set of tools for data analysis that resides inside the data warehouse.
Teradata Warehouse Miner provides and interface for data mining on Microsoft Windows. It was released before 2003.
The Aster Platform is Teradata's analytic technology, acquired from Aster Data Systems.
Backup, archive, and restore
BAR is Teradata's backup and recovery system.
The Teradata Disaster Recovery Solution is automation and tools for data recovery and archiving. Customer data can be stored in an offsite recovery center.
The Teradata database includes a feature called QueryGrid,  that allows user of the Teradata database to fetch data from external databases from standard SQL queries, as if they were hosted in the local EDW. The data movement happens in parallel whenever possible, so it is as efficient as performance the external data source; this is usually still much slower than native Teradata database performance, but still acceptable for exploratory tasks. External data sources are Aster, Presto, Teradata, Hive and Oracle.
Teradata Platform Family is a set of products that include the Teradata Data Warehouse, Database, and a set of analytic tools. The platform family is marketed as smaller and less expensive than the other Teradata products.

Teradata began to market with the term "big data" in 2010. CTO Stephen Brobst attributed the rise of big data to "new media sources, such as social media." The increase in semi-structured and unstructured data gathered from online interactions prompted Teradata to form the "Petabyte club" in 2011 for its heaviest big data users.
The rise of big data resulted in many traditional data warehousing companies updating their products and technology. For Teradata, big data prompted the acquisition of Aster Data Systems in 2011 for the company's MapReduce capabilities and ability to store and analyze semi-structured data.
Teradata's main competitors are similar products from vendors such as Oracle, IBM, Microsoft and Sybase IQ. Also, competitors include data warehouse appliance vendors such as Netezza (acquired in November 2010 by IBM), DATAllegro (acquired in August 2008 by Microsoft), ParAccel, Pivotal Greenplum Database, and Vertica Systems (acquired in February 2011 by HP), and from packaged data warehouse applications such as SAP BW and Kalido.
Teradata has also seen competition from Hadoop-based distributions and other open source technologies.
