Big data is a set of data that by its volume, nature, and speed at which it is to be processed exceeds the capacity of common computer systems.
The source of this volume of data can be very diverse: from the behavior of users when browsing the Internet to industrial environments that have many sensor elements. Big data technologies make it possible to extract useful information from the data in order to obtain statistical reports and predictive models, which favor better decision-making. Generally, big data can be described according to the following characteristics:
- Speed: Data processing needs to be done in real time, with the challenge that comes with it.
- Volume: Large data dimensions that require special technology to be stored and processed.
- Variety: different types and structures of data that come from very different sources.
