Big Data

Several definitions exist for Big Data, here are the ones I prefer:

  1. A collection of data sets so large and complex that it becomes difficult to process using on-hand database management tools or traditional data processing applications.
  2. When the data could not fit in Excel (used to be 65,536 lines, now 1,048,577 lines).
  3. When it's cheaper to keep everything than spend the effort to decide what to throw away.
