Just like a scientist using the scientific method, a data scientist looks closely and observes data – they generate questions and are naturally curious about the data being observed. They also use various mathematical and statistical algorithms to better understand the data and better answer the questions being asked.
Data science is an emerging field of study that creatively solves problems and extracts knowledge from data using mathematics, statistics, and computer science knowledge and skills. A data scientist has the ability to take data, understand it, process it, extract value from it, visualize it, and communicate what it means. As you can see from this description, many skills are needed for a data scientist, not just database and computer science skills.
