Teradata said Thursday it plans to buy data warehousing startup Aster Data Systems, continuing a run of consolidation in the market for technology that can process ever-growing amounts of "big data."
The deal is expected to close in the second quarter. Teradata, which had already acquired an 11 percent stake in Aster Data last year, will pay another US$263 million for the remainder, according to a statement.
"Big data" refers not only to the scope of today's information but also to the presence of both structured and unstructured data "involving complex interrelationships that do not lend themselves to analysis with today's traditional techniques," Teradata said.
While Teradata is already a well-established player in data warehousing, Aster's technologies will help it tackle the challenge of analyzing such workloads, it added.
The Aster Data acquisition is the second significant purchase by Teradata in recent months as it seeks to broaden its market footprint. Last year, it scooped up integrated marketing software vendor Aprimo for $525 million.
