Data streaming is the real-time transfer of data at a high speed, from one place to another through a network. Data streams are transmitted through the internet and can be processed and visualized to provide real-time insights.
A number of websites and social media services provide interfaces to access real-time data, which may be monitored by NGOs, for instance, during large-scale events like elections.
Other types of live, streaming data include weather and climate data, internet searches, and flight tracking data, as well as CCTV video and some satellite imagery.
