Teradata has agreed to buy consulting firm Think Big Analytics, marking the data warehouse firm’s third acquisition of a company specialising in big data within six weeks.

The deal was closed on Friday for an undisclosed amount.

Teradata, which has over 5,000 workers, said it plans to integrate Think Big Analytics’ consulting practice, which offers big data services, assessments, planning and architecture mapping, with its own big data consulting outfit in the Americas.

"Teradata and Think Big share an empowering vision to help customers leverage new, open source technologies to complement existing proven technologies, which drive analytic value from a rich diversity of data sets," said Ron Bodkin, founder and CEO of Think Big

Mike Koehler, president and CEO of Teradata, added: "Think Big’s consulting expertise enhances Teradata’s capability to advise customers on the best way to leverage diverse, open source big data technologies to grow their business."

The deal comes after Teradata bought assets from metadata management startup Revelytix and Hadapt in late July.
