Jack E. Shemer

Jack E. Shemer was co-founder and chief executive officer of Teradata Corporation, the company that created one of the first commercially successful massively parallel relational database systems. Under his leadership, Teradata developed high-performance data warehousing systems that became essential tools for large enterprises managing vast quantities of transactional and analytical data.

Shemer guided Teradata from its early engineering roots into a leading enterprise technology company, forging early partnerships with major industries including telecommunications, retail, and financial services. Teradata systems were instrumental in enabling large-scale analytics and business intelligence long before the terms became mainstream.

He also served in senior technology and engineering roles before founding Teradata, bringing strong systems and hardware expertise to the challenge of scaling relational databases to unprecedented performance levels.

Shemer’s work helped create the modern market for enterprise data warehousing and influenced decades of development in large-scale analytics, parallel processing, and data-driven decision-making.
