What is Data Analytics?
The 21st century has witnessed an extraordinary phenomenon—the rapid and voluminous surge in data generation. In perspective, a staggering 90% of the world’s total data has emerged in just the past few years.
The meteoric rise and spread of the internet, accompanied by the massive decrease in the storage cost of data, which has fallen from $300,000 for a GB (gigabyte) in 1981 to $0.10 by 2010, speaks volumes of the data revolution. The availability of huge amounts of data has led to various techniques that allow us to use this data to achieve numerous goals.
These techniques of analyzing data in modern times are collectively called Data Analytics. As this term is in high usage and is thrown around in almost all business domains, with each interpreting it in its way, it is easier for its definition to get lost in the translation.
From a non-domain-specific point of view, Data Analytics means the scientific usage of numerous statistical and programming tools to analyze the data through statistics, mathematics, and visualization.
