The Data Warehousing Strategy at Credit Suisse Financial Services
Credit Suisse Financial Services, Switzerland
Data Warehousing is not new to Credit Suisse Financial Services. Over the past twenty years, a large number of warehouse-flavoured applications have been built, ranging from simple data pools, to classical management information systems, up to novel customer relationship management support using state-of-the-art data mining technologies.
However, these warehouse projects were neither coordinated nor are they based upon the same infrastructure. Moreover, dramatic changes to the business design had a huge impact on the information analysis requirements. Both together resulted in a nearly unmanageable complexity.
Hence, Credit Suisse Financial Services started a 3-year enterprise-wide data warehouse re-engineering initiative at the beginning of 1999. This talk presents the motivation, experience and pitfalls of this comprehensive IT project.
Markus Tresch studied Computer Science and Economics at the Swiss Federal Institute of Technology (ETH) Zurich and received his PhD from the University of Ulm, Germany, in 1994. He spent a year as a visiting scientist at the Multimedia Information Systems Group of the IBM Almaden Research Centre, California, followed by a senior research associate position at ETH Zurich, where he led a research group in the area of distributed object management.
In 1997, he quit academia and joined Credit Suisse Financial Services, the second largest Swiss bank and one of the biggest IT employers in Switzerland. As a lead systems architect, he designed the enterprise wide data warehouse architecture and infrastructure. Today, he is director of Middleware Services, an IT Systems Engineering Department with 75 people managing more than 25 engineering projects, including data warehouse architecture and infrastructure.
