What is Data Science and who is a data scientist? If you are looking to advance your career in data and analytics or if you want to embark on a data science career, you might be asking yourself these questions. You may even have a few good answers in your mind as well. Below I’ll give you my definitions based on my experience as a Senior Data Scientist as well as an overview of data science’s impact on industry.
