India, Mumbai, February 26, 2007 - Patni Computer Systems (BSE: PATNI COMPUT, NSE: PATNI, NYSE: PTI) today announced that it has been ranked the strongest global services provider by ARC Advisory Group in strategic consulting for Master Data Management.

ARC Advisory Group evaluated the capabilities of leading global services providers for implementing Master Data Management (MDM) solutions and for providing high end consulting with respect to data quality and governance issues.

Master Data Management solutions support the global identification, linking, and synchronization of all data elements related to customers, products, and other classes of master data. An MDM can serve as a central system of record, either by creating and managing a central database or through the use of a metadata layer that can pull a desired data attribute into a single view of the truth.

As a result, business executives get more relevant and reliable information enabling them to make more effective decisions.

Our focus has always been on helping clients in leveraging technology for strategic business advantage. We strongly believe that Data Quality, Metadata management and Governance are critical to the success of MDM initiatives."

The MDM market is expected to grow rapidly for the next five years to become one of the fastest emerging software markets. The worldwide market for MDM is expected to grow at a compounded annual growth rate (CAGR) of 14.7% over the next five years. The market at $680 million in 2006 and is forecasted to be over $1.35 billion in 2011, according to a new ARC Advisory Group study, 'Master Data Management Worldwide Outlook'.
