 Big data needs no introduction however, we must provide one in order to give context to the subject of this article. Gartner’s definition, (circa 2001) (which is still the go-to definition): Big data is data that contains greater variety arriving in increasing volumes and with ever-higher velocity. This is known as the three Vs. In simple terms, big data refers to large, more complex data sets that is derived from a new data source. These data sets are so voluminous that using traditional data processing software alone cannot manage or process them. Data, of course, has several types which brings us the subject matter. Data is described to be of several varieties and they most found in two ways; this can be structured or unstructured. Structured type of big data simply put are that data that can be processed, stored and retrieved in a fixed format. Structured data are well organized and they can be readily and seamlessly saved and accessed by using simple search engine algorit...

Emerging Technologies: Blockchain A blockchain is a chain of blocks that stores data progressively, and it is not possible to backdate or damage them. It is a distributed storage that every user can get a genuine copy to avoid that someone else can alter. Users with a copy of this data can add new records to it, but they cannot change what is already contained. This feature makes blockchains a fantastic asset to record information with transparency because everyone keeps an eye on it and can notice that the data is being used well. (Decuyper, 2021) A blockchain is also a trustworthy platform that supports and stores data over a network of personal computers connected; this data could be verified by every user accessing this information worldwide. The security of this system is fully guaranteed as every user can watch what is happening with the data in real-time. This mechanism is decentralised and distributed; in other words, there is no central institution or person who is the ho...

Big Data, one of today's popular concepts, was first introduced in the field of astronomy and genetics, and with the introduction of the internet into our lives, it has gained a different dimension and has become a resource that we have a share in its growth without realizing it. Before looking at the definition of big data, we need to look at the equivalent of the data in the literature. Data refers to a general term derived from research, observations, internet, social media, and sensors. Big data; It is the form of data that is analyzed and classified, transformed into meaningful and processable form. When interactions in constantly used social media accounts, search engines and traces left behind when searched, movements made with bank accounts, blogs, mails, sensors and individual users' interactions with the internet are brought together, a huge data stack is formed. We can evaluate big data as a treasure that feeds from this stack and presents meaningful and actionab...
