It is connected to the net and it generates informations (data) whose huge dimension (big) can be used in order to create business analysis, research and development, marketing, etc. The Big Data are considered as “a data storing as much big and complex as different tools than the traditional ones are required to be analyzed and seen.” Their main features are:
- Volume: taking over, memorizing and entering huge data volumes skills;
- Speed: data analysis in real time o nearby;
- Variety: referring to different data typology, coming from different sources.
Some Open Data and Big Data potentials coming from their analysis are the following:
- Massive services’ customization;
- Quicker answers to market’s trends;
- Real time identification of costs’ optimizations;
- Quicker and more careful decisions;
- Better research and more emphatic development about complex systems.
