What Is Big Data?
Data sets too vast for common software tools to handle.
A movement to efficiently mine and analyze all of this data to find patterns, spot trends, and make effective decision.
The result of our expanding ability to create & capture data and our ever expanding ability to store all of that data.
It is as much current data that has been born digital as it is past information that has been digitized.
Massive amounts of digital data being created and accumulated consciously and unconsciously in the digital world we live in.

If we provide access to data, do we leave it in its native format or provide services to transpose the data to a different format? (The Signal: "Big Data and the Dawn of the Super Researcher" by Mike Ashenfelder)
What kind/how much training/support do we provide the public?
Nowcasting ("Now" + "Forecasting")
