BigData - Volume, Variety, Velocity (and Variability?)
IBM seemed to have the definitive word in the definition of BigData, i.e.,
To the above, Forrester (hidden behind a paywall, of course), wants to add a fourth term
- Volume - Quantity. D-uh.
- Variety - Different types of data, such as audio, video, text, etc.
- Velocity - The rate at which this data changes
To the above, Forrester (hidden behind a paywall, of course), wants to add a fourth term
- Variability - The different meanings/contexts associated with a given piece of data
It does makes sense. I have always referenced Variety to subsume Variability, but it probably makes sense to call it out as its own distinct entity.
