Millions of users access the Internet every day, whether to work, make purchases online, consult social networks or simply look for information at the moment. In this sense, every time a person enters a web page a “pop-up” appears with the Cookies policy of the site in question with options to reject, configure or accept, so we always click on the last option to be able to continue browsing the network, thus opening the door to personalized advertising.

Cookies are a file that contains information about the actions that have been carried out on a web page and accepting them implies a personalization of advertising, among other consequences. Therefore, from then on, any navigation made on the internet or social networks may contain advertising for previously searched products or of content of interest to the user.

“Personalized advertising is a set of strategies that allow companies to offer differentiated products and services for each client”, as explained by the leading technology training school, Ironhack. Therefore, in this way, messages are designed that impact the consumer “incessantly” in search of clicks, which implies a constant generation of data, so that any movement or update on the Internet will create new information that will lead to a great volume of information known as Big Data.

In this context, the volume of data generated worldwide will exceed 180 zettabytes in 2025, which means an average annual growth of almost 40% in five years especially as a result of the boom in social networks and the extension of 5G, as revealed by Statista data. Therefore, it is not surprising that the Big Data market is growing worldwide, and in Spain it is increasing by 30% each year, according to data from the Cotec Foundation.

The Big Data is that discipline that processes and analyzes large amounts of data collected on the Internet, scientific instruments, mobile devices, and sensor and network technology. Therefore, from Ironhack they point out that analysts in this discipline can anticipate future scenarios since they know the consumer better, adapting the information and also increasing sales.

However, not everyone can dedicate themselves to this profession, but to be a data analyst, from this school they explain that a combination of “passion for statistics, algorithms, management of complex data structures and basic knowledge of engineering is necessary. of software”. So, given that these professionals provide companies with a lot of substantial information, this causes a wide variety of jobs to be generated from administrator or data engineer to “data artist” or data scientist, among others.

“Today, processing and analyzing the enormous amount of data that is created every minute is a pressing need. This is an increasingly present reality in the business world. Currently, at data analyst is considered one of the most growing and demanded jobs thanks to its essential utility”, says Miguel Enríquez, Lead Teacher Data Analytics at Ironhack.
