Data Scientists are professionals who can analyze and explain complex digital data. They organize varying data elements with various techniques including signal processing, mathematics, probability models, machine learning, statistical learning, computer programming, visualization, data warehousing, and high performance computing with the goal of extracting meaning from data and creating data products.

To start your career as a Data Scientist, you are required to having a clear knowledge in Data Science. A Data Scientist dealing with the big data an important aspect of data science. In fact, data science is such a relatively new and rising discipline that no one can easily learn it without any training program to be become a data scientist

Demand of Data Scientist

A lot of companies and industries have dramatically increased investments in their digital platforms in the past few years. It has been estimated that by 2020, IT departments will be monitoring 50 times more data than they are today. This tidal wave of data is driving heavy demand for Data Scientist to manage these very large data sets into a competitive advantage.

The study warns there is a significant shortage of qualified Data Scientist to analyze big data sets adequately. According to the report, a shortfall of about 140,000 to 190,000 individuals with analytical expertise is projected by 2018.. The study also predicts a need for an additional 1.5 million managers and analysts by that same date to fully engage the true potential of the currently available data.

Thousands of data scientists are already working at both start-ups and well-established companies. Simply put, if any organization stores multiple petabytes of data, you’ve an opportunity there.
