| Working with Sun Microsystems and Accenture, Visa EU has created one of the Europe’s largest data warehouses to store details of the 3 billion credit and debit card transactions it processes every year across 26 different countries.
Banks will be able to interrogate the data in various ways to uncover changing trends in the economy generally, and in more detailed spending patterns, all within the strict regulatory framework of the EU Data Protection Directive. Individual customer data is not identified.
VISA EU’s 6,000 member banks will also be able to benchmark themselves against their competitor peer group on a range of key business indicators and consumer behaviour.
Visa EU also sees the capability of its data warehouse as potentially being attractive to research houses who rely heavily on the analysis of raw data, and to merchants who need to know about changing spending patterns - although there are no firm plans in this area yet.
The unique ability of Visa to analyse trends in the European economy becomes crystal clear when we look at how central a role the world’s biggest payment card provider now plays in the economy. Consider some of these facts recorded by Visa EU at the end of 2001; 194 million Visa cards in European circulation (up 10%), €683 billion annual expenditure (up 17.5%), 10 billion transactions a year (up 16%).
Visa EU processes by far the largest number of those 10 billion transactions. All international transactions, for example, pass through Visa EU’s networks and a large amount of domestic transactions from a number of countries including the UK, Sweden, Italy and Germany. The power of Visa’s information stems precisely from this ability to take the wider view; across member banks, across countries, across different sectors, and so on.
Sitting at the heart of this ambitious project is a framework of Sun Microsystems technology which will allow the uninterrupted processing, storage, archiving and speedy retrieval of all Visa EU credit card data whenever required.
Visa accepted Accenture's recommendation that the SUN 6800 Sun Fire server be implemented as the Data Warehouse server. Accenture has integrated a powerful structure for a data warehouse which can handle 20 million transactions a day. In addition, 4800 Sun Fire server is used for the development and testing environment.
The combination of 6800 and 4800 Sun Fire servers powered by Sun's high performance UltraSparc III processors, allied to 12 terrabytes of T3 storage - all running on the Solaris 8 operating system – has created a powerful structure for a data warehouse which must handle three billion transactions a year.
