Kelley Blue Book’s website, kbb.com, leverages Netezza’s data warehouse to help gather, analyze and distribute data from many different sources faster to provide vehicle buyers and sellers with the most-up-to-date pricing and values.

With the TwinFin appliance, Kelley Blue Book combined advertising, revenue and site traffic data to gain a comprehensive, multi-channel view of its business and increase customer satisfaction and overall advertising revenue. kbb.com, a premier online destination with more than 18 million online visits per month, also dramatically reduced the amount of time it took to process data for a variety of purposes. For instance,kbb.com is now able to process vehicle valuation in a day, producing values that can be delivered in near real-time to the marketplace. Kelley Blue Book also leverages the TwinFin appliance to perform advertising forecasting for up to 12-24 months in advance, enabling the company to increase advertising revenue, enhance insight into ad performance and create more reliable and accurate ad forecasting and analysis for its advertisers.

"KBB understands the importance of advanced analytics and has further integrated it into the company's core business strategy. With Netezza, we can leverage analytics to provide clients with more accurate user information within minutes, instead of days,” said Dan Ingle, vice president of analytic insights, Kelley Blue Book. “Since implementing the TwinFin appliance, we’ve increased ad revenue and overall customer satisfaction through faster and more accurate analysis. Our customers routinely praise the analytic insights we deliver to them as being the best in the industry.”

It stores, filters and processes terabytes of records within a single unit, analyzing only the relevant information for each query. Netezza has placed the CPU power next to the data, allowing its appliances to speed through processes that would occupy most data warehouse systems for hours, or even days.
