In today’s generation data is something you will find everywhere. It is growing at a rapid rate, data is the thing which is doubling every two years and changing our day to day life and the way of living. About 1.7 megabytes of new information will be created every second for every human being on the planet, which makes it extremely important to know the basics of the field at least. After all, here is where our future lies.
Here we will differentiate between the Data Science, Big Data and Data Analytics, based on how it is, what it is, where to use, the skill you need to know and the salary in each field.
Let’s first start with understanding what these concepts are.
What is Data Science?
Data Science is the combination of statistics, mathematics, programming, problem-solving, capturing data in ingenious ways, the ability to look at things differently, and the activity of cleansing, preparing, and aligning the data. It deals with both unstructured data and structured data also the data science is related to data cleansing, preparation, and analysis.
