Leveraging data in innovative ways offers businesses unparalleled opportunities to understand and respond to the needs of a rapidly moving and changing market. Yet as an increasing volume of data from ever-growing numbers of sources pours into data centers, today's enterprise is just as likely to drown in its data as it is to harness it for a strategic market advantage. The sheer volume of data-terabytes and increasingly peat bytes of information-suggests why managing and analyzing it is a challenge. It's no longer efficient for Data Warehouses (DWs) to manage single, homogenous workloads. Business analysts need access to a wide variety of data, in real time, for diverse uses such as standard and specialized reporting, OnLine Analytical Processing (OLAP), advanced analytics such as data mining and data marts and staging for detailed or real-time data sources.
