The networking of the real world with cyberspace makes it necessary for the machines used to be able to draw the right conclusions from the knowledge gained. For example, data volumes can consist of observations of the market as well as video files in other cases. The latter are very interesting for supermarkets, for example. It is important for them to know which target groups, such as families or senior citizens, can be expected at which times.
However, big data analyses can go a decisive step further here and also interpret their mood based on facial expressions, for example. In addition to the mere sales figures, the owners also know which presentation of new products has met with the approval or rejection of customers.
Real-time analysis is an important factor in the industry. In today's regional, national and global competitive situations, companies need to receive analysis results as quickly as possible. Real-time analyses not only show short-term trends, but also feed the databases with every new second in order to achieve increasingly accurate results over the course of days, months and years.
