Introduction to Data as a Service via Social Media

I read this article several weeks ago which introduced me to the concept of Data as a Service (which does seem to be a natural extension of the I(nfrastructure)aaS, P(latform)aaS and S(oftware)aaS that we all know and love already.  The slides really do the introduction justice as the example is easy to understand for how social media is digested and analyzed between "public data" or application data among many different dimensions.  It is also an extension of the Oracle Cloud offering as well, since the KPIs and other devices which you can use to gather data really belong in a large repository type receptacle with easy to use features.  Great article, very informative, and just touches the surface of a new concept enough that I want to go out and learn more.
