In the competitive world of business, the survival of a company depends on how fast they are able to recognize changing business dynamics and challenges, and respond correctly and quickly. Companies must also anticipate trends, identify new opportunities and transform their strategy to stay ahead of the competition. Companies collect significant volumes of data. They need the ability to transform this raw data to actionable information by capturing, consolidating, organizing, storing, distributing, analyzing, and providing quick and easy access to it.
