Today’s organizations face growing challenges extracting business value from their data: First, the relentless growth of data continues, due to the proliferation of new devices and sensors, and rapidly declining hardware cost. More organizations now store terabytes and even petabytes of data. Second, data complexity is increasing as customers store both structured data in relational format and unstructured data such as Word or PDF files, images, videos and geo-spatial data. Indeed industry analysts confirm that over 80% of data captured is in unstructured format. Finally customers are also challenged by the velocity of data – organizations that process streaming data such as click streams from web sites, need to update data in real time to serve the right advert or present the right offers to their customers.
