Abstract
The unimaginable speed of the development of information and communication technologies has led to the fact that in the time period from 2009 to 2012, human society generated and saved more information than in the entire history until then. As estimated in 2013, approximately 1,200 exabytes were generated around the world, and this vast amount of information is doubled every three years. This would mean that estimated amount of generated data for 2019 is approximately 4800 exabytes, that is, three times more than the total amount information generated throughout the history. Since such a large amount of information cannot be stored or processed (and especially not in real or reasonable time) using the common methods of storing and processing data, a new paradigm of storage, processing and management of large quantities, variety and data processing speed has emerged under the name big data concept.
TopIntroduction
In order for the company management to successfully manage the company, it is necessary to make the right (quality) decisions at all times. In order to make good decisions, it is necessary to manage the data in a good way, and a priority condition for this to be possible is that the data must be accurate, complete, timely, consistent, accessible, relevant and concise. Good data management and analysis have always been the greatest strengths and the biggest challenges for all companies. Unfortunately, the process of collecting, storing, managing and analyzing this data is becoming more demanding, but at the same time, easier and more useful for companies, thanks to the incredibly fast development of information and communication technologies.
Companies have long struggled to find the simplest approach to collect information about their customers, products and services. When the company had only a small number of customers, and when they were all buying the same or similar products in the same or similar way, things were quite simple. But over time, the number of companies doing the same business was increasing, the markets in which they participate were expanding, so things about data management become more complicated. To survive or gain a competitive advantage, these companies have expanded their product range by adding more product lines and introducing a variety of product delivery methods.
