India is contributing 6% of job openings of it. Below, we are going to jot down pre-requisites of Data Science which will help you to reach out to great heights in the career of Data Science.

What is Data Science?

Data Science is a meadow that makes use of scientific methods and algorithms to extract knowledge and gain insights from structured and unstructured (raw) data. With the understanding of Science, Data Science is valueless, and trying to achieve something with it may be a fruitless effort; because Data Science is 90% of Science and only 10% of the management of data.

What is Data Scientist?

Data Scientist is a professional with the capabilities to collect a large amount of data to analyze and synthesize the information into the actionable plans for the organizations. Data scientists may present the data in a visualized manner. They often create highly advanced algorithms that are used to determine patterns and take the data from a muddle of number and stats to something that can be useful for business. In this profession, technical skills are not being counted. On the other hand, Data Scientists often exist in business settings and are charged with making complex data-driven organizational decisions.
