CIOs understand the importance of analytics and BI. According to a 2012 survey of 2300 CIO by Gartner, analytics and BI are their number one technology priority. Analytics and BI can make bigger business impact when they can access more data. With data in the cloud and Big Data silos, accessing and integrating these new sources can be a challenge for enterprises used to a traditional enterprise data warehouse centric data integration approach. Data virtualization enables integration of cloud, Big Data and enterprise data warehouse sources with ease and agility.
