Data Science and Data Scientist Requirements

Data science uses the most powerful hardware, programming systems, and most efficient algorithms to solve the data related problems.

What is Data Science?

Data science is an interdisciplinary field that uses scientific methods, processes, algorithms and systems to extract knowledge and insights from noisy, structured and unstructured data and apply knowledge from data across a broad range of application domains.

In the other words, we describe a data science is all about:

• Modeling the data using various complex and efficient algorithms

• Visualizing the data to get a better perspective

• Asking the correct questions and analyzing the raw data

• Understanding the data to make better decisions and finding the final result
