The story of Teradata begins in the early 1970s at the California Institute of Technology (Caltech). A team of researchers, including Dr. Edgar F. Codd, set out to explore the possibilities of parallel processing for database management. Their efforts led to the development of the world’s first parallel database system, named Teradata.

1979 – Formation of Teradata Corporation:
In 1979, Teradata Corporation was officially founded in Brentwood, Tennessee. William (Bill) N. Howar, along with his colleagues, Gary A. Minne and Philip M. Neches, established the company with the vision of commercializing the innovative parallel processing database technology developed at Caltech.

1980s – The Decade of Firsts:
The 1980s marked a period of significant milestones for Teradata. In 1983, Teradata introduced its first commercial database management system, Teradata Database/2000, designed for parallel processing. This system laid the foundation for what would become Teradata’s renowned scalable architecture.

In 1986, Teradata made history by launching the world’s first terabyte-sized database for the U.S. Air Force, showcasing its capability to handle massive volumes of data.

1990s – Expansion and International Reach:
Teradata continued to expand its presence globally during the 1990s. In 1991, Teradata introduced the Teradata 2 database server, which featured enhanced performance and scalability. The company’s success in providing data warehousing solutions led to increased adoption across various industries, including telecommunications, finance, and retail.

In 1997, NCR Corporation acquired Teradata Corporation, further solidifying its position in the data warehousing market.

2000s – Teradata as an Independent Company:
In 2007, Teradata became an independent public company after a spin-off from NCR Corporation. This move allowed Teradata to focus exclusively on its data warehousing and analytics solutions, leading to increased innovation and a renewed commitment to meeting the evolving needs of its customers.

During this period, Teradata continued to advance its technology with the introduction of new platforms, such as the Teradata 12.0 Database in 2008, featuring improvements in scalability, performance, and manageability.
