dunnhumby increases customer loyalty with Oracle Big Data

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.

Swiss Re increases data warehouse performance and deploys in record time

Great information on yet another data warehouse deployment on Exadata.

A little background on Swiss Re:

In 2002, Swiss Re established a data warehouse for its client markets and products to gather reinsurance information across all organizational units into an integrated structure. The data warehouse provided the basis for reporting at the group level with drill-down capability to individual contracts, while facilitating application integration and data exchange by using common data standards. Initially focusing on property and casualty reinsurance information only, it now includes life and health reinsurance, insurance, and nonlife insurance information.

Key highlights of the benefits that Swiss Re achieved by using Exadata:

  • Reduced the time to feed the data warehouse and generate data marts by 58%
  • Reduced average runtime by 24% for standard reports
  • comfortably loading two data warehouse refreshes per day with incremental feeds
  • Freed up technical experts by significantly minimizing time spent on tuning activities

Most importantly this was one of the fastest project deployments in Swiss Re's history. They went from installation to production in just four months! What is truly surprising is the that it only took two weeks between power-on to testing the machine with full data volumes! Business teams at Swiss Re are now able to fully exploit up-to-date analytics across property, casualty, life, health insurance, and reinsurance lines to identify successful products.

These points are highlighted in the following quotes from Dr. Stephan Gutzwiller, Head of Data Warehouse Services at Swiss Re: 

"We were operating a complete Oracle stack, including servers, storage area network, operating systems, and databases that was well optimized and delivered very good performance over an extended period of time. When a hardware replacement was scheduled for 2012, Oracle Exadata was a natural choice—and the performance increase was impressive. It enabled us to deliver analytics to our internal customers faster, without hiring more IT staff"

“The high quality data that is readily available with Oracle Exadata gives us the insight and agility we need to cater to client needs. We also can continue re-engineering to keep up with the increasing demand without having to grow the organization. This combination creates excellent business value.”
