SAND Technology Inc., an innovator in analytic application infrastructure, released additional results from an independent research study by Dynamic Markets Limited entitled "The Crumbling Foundations of Data Warehouses". The research reveals that, while data warehouse managers acknowledge that the value of the data stored changes over time, few have the technology architecture in place to address this.

According to the survey of data warehouse managers in the Top 2000 UK companies, more than 90 per cent of respondents recognize that the value of business data changes over time. However, less than a quarter (25 per cent) have fully implemented data management strategies in place that specifically address this, despite the fact that nearly a third (32 per cent) think that it costs significantly more to carry out queries on old, out-of-date data than on current information.

Commenting on the results of this research, Robert Thompson, VP Marketing at SAND Technology said: "It's amazing to think that data warehouse managers know that querying old data is more expensive than newer data, yet so few have systems in place to manage the fact that data values change over time. Our current business climate of compliance and regulation means that increasing amounts of data and information need to be stored for longer periods of time, and it is obvious that the value of this data changes as time and circumstances change. In order to run an efficient, cost-effective warehouse infrastructure, we believe that it is imperative that systems are put in place to manage the storage and retrieval of information in a flexible, yet secure, way and I am alarmed to see that still so few companies appear to recognize this."
