Big data

PrepNuggets

Widely-used expression that refers to all the potentially useful information that is generated in the economy. This includes not only data from traditional sources, such as financial markets, company financial reports, and economic data, but also alternative data from non-traditional sources like:

  • Individuals who generate usable data such as social media posts, online reviews, emails, and web searches.
  • Business processes that generate potentially useful information, such as credit card transactions, direct sales information, and corporate exhaust.
  • Data collected by sensors, such as smart phones, cameras, RFID chips, which are increasingly being extended into a broad network known as the Internet of Things.
