Keith Laker
Senior Principal Product Manager

dunnhumby presented at this year's OpenWorld where they outlined the how and why of data warehousing on Exadata.  Our engineered system delivered a performance improvement of more than 24x. dunnhumby pushes its data warehouse platform really hard with more than 280 billion fact rows and 250 million dimension rows for one large retailer client alone, dunnhumby’s massive data requires the best performance the industry has to offer.

In Oracle Exadata, dunnhumby has found that solution. Using Oracle Exadata’s advanced Smart Scan technology and robust Oracle Database features. This new environment has empowered its analysts to perform complex ad hoc queries across billions of fact rows and hundreds of millions of dimension rows in minutes or seconds, compared to hours or even days on other platforms. 

You can download the presentation by Philip Moore - Exadata Datawarehouse Architect, Dunnhumby USA LLC -  from the OpenWorld site, see here: https://oracleus.activeevents.com/2013/connect/sessionDetail.ww?SESSION_ID=3412.

If you missed Philip's session at OpenWorld then we have just released a new video interview with Chris Wones, Director of Data Solutions at dunnhumby. During the interview Chris outlines some of the challenges his team faced when trying to do joined up analytics across disparate and disconnected data sets and how Exadata allowed them to bring everything together so that they could run advanced analytical queries that were just not possible before and that meant being able to bid on completely new types of contracts. The combination of Exadata and Oracle Advanced Analytics are delivering real business benefit to dunnhumby and its customers.
