Telco Industry: Leading Provider for Billing and Collection Services Migrates to Teradata Warehouse

Superior performance, lower costs and distinctive customer orientation

April 3, 2006, DAYTON, Ohio – Teradata, a division of NCR Corporation (NYSE: NCR), is now supporting ActiveBilling, T-Systems’ division for billing and collection services, in developing a new data warehousing platform. The first step—migrating the data warehouse from its current IBM platform to Teradata—will be accomplished by the end of 2006.

Once the migration is completed, the new ActiveWarehouse—as the company has named its data warehouse—will process data generated by approximately 960 million billings for 40 million customers. According to the current plan, subsequent project stages encompass the following areas:

• Data warehouse user services for further clients of the division with ActiveWarehouse accounts
• Incorporating new data sources
• Providing further external aggregate systems to current and future clients
• Integrating business intelligence tools.

With its expertise in data warehousing solutions, Teradata will provide its partner with the means to further develop its data warehousing capabilities.

High expectations

The Teradata team’s capabilities prevailed after a complex evaluation and selection process. One objective to be met was that the total cost of ownership must be only 50 percent of that of the current solution. Another objective was a dramatically improved recovery capability. Other important criteria included increased storage efficiency, practically linear hardware, software solution scalability, smooth integration capability through standardization and open architecture, a strong information lifecycle management concept and ease of use and management.

In a test run conducted in the summer of 2005, the Teradata platform was evaluated against more than 100 criteria. Teradata’s team successfully brought to bear its many years of experience on the enormous data volume at hand and responded correctly to the test run’s ad hoc queries. In terms of throughput time and quality, Teradata’s robust interfaces and aggregates performed compellingly well. The proof-of-concept testing was conducted at the company’s Frankfurt-based IT center.
