Big data in cloud
pervasively invading industry and society, both drowning in information overload. [2]
Big data can be described by the following properties:
- Volume. Organizations collect data from a variety of sources, including business
transactions, social media, and information from sensor or machine-to-machine data.
In the past, storing it would’ve been a problem – but new technologies (such as
Hadoop) have eased the burden. [3]
- Velocity. Data streams in at an unprecedented speed and must be dealt with in a
timely manner. RFID tags, sensors, and smart metering are driving the need to deal
with torrents of data in near-real time. [3]
- Variety. Data comes in all types of formats – from structured, numeric data in
traditional databases to unstructured text documents, email, video, audio, stock ticker
data, and financial transactions. [3]
