The Intelligent Thing -- Using In-Memory for Big Data and Beyond

326

Published on

The Briefing Room with John O'Brien and Teradata
Live Webcast on June 11, 2013
http://www.insideanalysis.com

For traditional Data Warehousing and Big Data Analytics, research shows that a small percentage of enterprise data often comprises the lion's share of what's needed for queries. That's hot data, and organizations that know how to effectively harness that data can stay on top of what's happening. Conversely, cold data can certainly provide value at times, but should ideally be stored in ways that minimize cost. The more dynamically a company can manage this hot and cold data, the more efficient its information systems become.

Register for this episode of The Briefing Room to hear veteran database expert John O'Brien of Radiant Advisors as he outlines a strategy for managing hot and cold data. He'll be briefed by Alan Greenspan of Teradata, who will tout his company's Intelligent In-Memory solution, which optimizes the management of hot and cold data to keep analysts fueled with the data they need most. He'll also discuss Teradata Virtual Storage, which helps optimize the storage and provisioning of information assets.
