Bracknell, Berkshire — 22nd July, 2008 — Netezza, the global data warehouse appliance market leader, today announced that The Phone House, the German subsidiary of The Carphone Warehouse is to replace its 4TB Oracle enterprise data warehouse with Netezza. The project forms part of The Phone House's ongoing BI strategy driven in partnership with its strategic Information Management consultancy and delivery partner, Acuma. The project aims to improve the performance and functionality of the data warehouse while reducing its maintenance overheads.

Klaus Zumdick, Head of Business Intelligence at The Phone House explained, "Our current data warehouse is failing to deliver queries in an acceptable time frame, and the latency of data over our network means it's no longer fit for purpose. The NPS system will allow us to massively reduce the time it takes us to load and recover business critical data. We currently have 500GB of indexes that take hours to load. Using the index-free Netezza data warehouse appliance will shrink these processes to literally minutes."

Andreas Gonzalez, Business Change Manager at The Phone House added, "The German business is undergoing a business transformation project in which the data warehouse plays a key part. Being able to perform detailed analytics in a telecommunications business is absolutely business critical. The previous platform was not able to offer this, or keep pace with our capacity requirements."

Bernard Doering, Country Manager, across DACH for Netezza added, "One of the most significant advantages to The Phone House will be the ability to access and analyse its data in significantly greater detail. For the first time, the Company will be able to analyse data such as calling patterns and customer churn which may be used to stabilise and manage its customer upgrade processes. Netezza is investing in establishing operations in Germany. Having customers in the country is significant to other German organisations considering this technology for their own data warehouse."

Alan Duncan, Consultancy Partner at Acuma concluded, "The Carphone Warehouse has been using Netezza for call detail record (CDR) analysis in the UK for some time. By early next year, we will have migrated The Phone House CDR and billing analysis to the NPS system, and this will be quickly followed by the financial applications and commission flows, until the warehouse is live across the entire German enterprise. There will also be an upgrade to Informatica Version 8 across the group, who will continue to use Business Objects as its main BI software tool, along with SAS for insight and data mining reports."

The NPS system is a data warehouse appliance built specifically to analyse terabytes of detailed data. It stores, filters and processes terabytes of data within a single unit, analysing only the relevant information for each query. This allows the NPS system to speed through processes that would occupy most data warehouse systems for hours, or even days, thereby enabling dramatic increases in productivity.
