Big Data pertains to any/all of the following
- Data may be captured at a rapid rate
- Data may be unstructured, or consists of a variety of structures. In other words, not well suited to a relational database
- Can’t easily mine the data using SQL. Extracting seems to be better suited to procedural algorithms
- Does not have to be a lot of data. Could be a few MBs, but it also could be a few petabytes.
