Montreal, Canada – February 24, 2009 SAND Technology Inc. (OTCBB: SNDTF.OB), an international provider of data management software and best practices, announced today that dunnhumby, a leading international marketing consultancy, is expanding its use of SAND/DNA to offer major retail clients around the world a better understanding of their customers. dunnhumby has been providing advanced customer analysis for over 20 years, and is now offering the same capability in the US, mainland Europe and the Far East using customer data from Kroger, Home Depot, Groupe Casino, and Tesco International.

The insights provided by dunnhumby’s SAND/DNA-based solution have enabled clients such as Tesco and their suppliers to increase their pool of loyal customers through improvements in pricing, promotions, and product assortment/ranging all aimed at improving relevance to customers. dunnhumby’s expanded offering builds on SAND/DNA’s ability to respond quickly to complex and unpredictable queries against extremely large volumes of data, while keeping administration requirements to a minimum and taking full advantage of cost-effective, easily scalable hardware environments. SAND and dunnhumby have furthermore agreed to work together to make the existing solution easily replicable, so that new customer installations can be made operational much more quickly.

“We chose to expand our SAND/DNA environment because of its speed advantages and the very competitive economies of scale it enables. We currently manage and interrogate very large volumes of data for a range of clients. Costs and administrative complexity can increase quickly when such large volumes are involved,” said Stuart Bonell, Chief Technology Officer, dunnhumby. “The easy data access, high-performance and high levels of compression provided by SAND/DNA ensure that we have increased visibility into all our clients’ data, as and when our analysts and clients need it.”

“We are very pleased to have dunnhumby as a partner”, said Arthur Ritchie, Chairman and CEO, SAND Technology. “Their global reach, expertise in the retail market and advanced data analysis solution offerings have helped make SAND/DNA a key component of the decision-making process in a number of very important companies.”

SAND/DNA enables enterprise customers in all industries to cost-effectively retain massive amounts of compressed data in a nearline repository for extended periods, in accordance with any applicable business rules and regulatory requirements, and to rapidly retrieve information when needed. A centralized data management solution with unparalleled performance and storage efficiency, the SAND/DNA suite dramatically reduces costs and management complexity while ensuring continuous data availability. Organizations can create data marts on demand to respond to any analytic requirement with all enterprise data — current or historical, detailed or summarized. SAND/DNA’s advanced information management technology compresses data to typically 10 percent of its original size, while giving users the ability to query any attributes of the data without decompressing it first. This next-generation capability is ideal for satisfying enterprise compliance requirements as well as for leveraging valuable information in data warehouses.
