The more you know about something or a situation, the more reliable your predictions about what will happen in the future.

The collection and analysis of data, or in other words, information, helps us understand the world we live in. Before computers came into our lives, people were collecting data to the extent allowed by their technology. Sometimes it was written tablets, sometimes it was paper.

When computers came into our lives, we started to keep data in databases. The data here is kept with traditional data processing methods. The data here is in an order. Consider an excel file where data is contained in a column and a column. The logic is almost the same in large databases.

What is Big Data ?

It is the name given to the operations used in cases where the data cannot be organized with traditional data processing methods and naturally cannot be made sense by these structures.

To explain this a little bit, data is now created by many devices. While you are uploading a photo to a social media platform, your mobile phone or the GPS in your car determines your location, mobile phones are recording you, using search engines, and watching videos, you inevitably create data. All of these, that is, the data created by the movements we have mentioned, are transmitted to various centers. Since they come from many different places (and these channels are becoming more diverse every day), the collected data needs to be structured, that is, put in an order. Here, algorithms and simulations that process this raw data and make it meaningful create big data. As it can be understood from here, the structured data is no longer just texts, but also consists of photographs, sounds and videos.

Therefore, while you are searching the web, browsing a site or watching a video on a topic, it is not a chance to come up with advertisements related to it.

Have you ever thought ?

How do the social media platforms or search engines that everyone knows and use offer their services for free (that is, they become the most valuable companies in the world) If they don't make money from these services, where do they make money? The answer is very simple. From ads. So why do people advertise on these platforms ?

The answer is not that they are very popular. Rather than popularity, it is the success of bringing the advertisement there to the desired target audience. So what is the secret of this success? Your movements on these platforms are analyzed very well with big data and they know which advertisement you will be interested in.

The fact that one of the world's largest social media platforms bought a messaging application that we all use for 19 billion dollars, that only a mobile phone number is needed instead of a username and password to use this messaging application, this social media platform is also the world's most popular photo uploading application. It should not be a coincidence that most of the photos uploaded here are taken from their mobile phones.
