Big data
The five Vs describe volume (amount), velocity (generation or processing speed), variety (forms and sources), veracity (reliability and uncertainty) and value (useful benefit). More data alone does not guarantee better decisions; governance, quality, security and appropriate analysis are needed.
Worked example
A retailer combines millions of transactions, live website clicks and customer comments to improve stock forecasts. It checks the sources and whether the forecasts improve availability.
Common mistake
Confusing data volume with data value or assuming a large dataset is accurate and representative.
